Are you ready for one of the best performing DAZA intakes on the market? The X34 Carbon Fiber Audi 8S TTRS and 8V.5 RS3 4” Closed-Top Upper Intake for the 2.5 TFSI EVO offers horsepower and torque gains throughout the powerband, with peak gains of up to 21 crank horsepower and 16 ft-lbs of torque on stock turbo tunes with 4” inlets.

034Motorsport engineers worked hard to develop a cold air intake solution for the TTRS and RS3 that yields horsepower and torque gains over the well-designed factory airbox, ultimately resulting in this beautifully-manufactured Carbon Fiber 4” Closed-Top Cold Air Upper Intake System.

NOTE: For 2019+ models, you must also purchase this adapter kit: 034-108-Z074

034Motorsport is pleased to present our X34 4” Carbon Fiber Closed-Top Cold Air Upper Intake System for the 2.5 TFSI EVO engine found in the 8S Audi TTRS and 8V.5 Audi RS3!

034Motorsport’s engineers spent extensive effort to develop a cold air intake solution for the TTRS and RS3 that yields horsepower and torque gains over the well-designed factory airbox. During the development process, many iterations were designed, prototyped, and tested, which resulted in this beautifully-manufactured Carbon Fiber Cold Air Upper Intake System.

DESIGNED FOR MODULARITY

034Motorsport engineers dissected the factory intake system, and identified the key weak points that it had for high performance flow. During this dissection, it was found that the largest restriction was the filter membrane, and the accompanying plastic accordion hose that runs to the turbocharger. The factory lower air box and fresh air duct, however, with some modifications, were found to be suitable for most stage 1 and stage 2 setups.

This drove the modular design that the X34 Evo intake systems all share, where the upper air filter system can be used both with the factory lower airbox and fresh air duct, and with the 034Motorsport X34 lower intake box and fresh air duct. This allows for the end user to purchase individual components to eliminate the largest flow issues, while still having a path to upgrade to higher flow and performance.

MAXIMIZING AIRFLOW

034Motorsport engineers first created a CFD-optimized carbon fiber intake tube, which is a direct, high-performance replacement for the plastic factory accordion hose. Using CAD software and 3D scanning technology, 034Motorsport was able to optimize the cross-sectional area of the intake tube while being mindful of space constraints. The resulting part is a functional work of art - maximizing performance given the factory space constraints and featuring smooth transitions that ensure optimal airflow to the turbo inlet.

MINIMIZING INTAKE AIR TEMPERATURE

To ensure that the 034Motorsport X34 Closed-Top Cold Air Upper Intake System draws in cool, dense air, the system includes a fully enclosed carbon fiber heat shield to replace the upper airbox as well as a stainless steel heat shield to block heat from saturating the intake tube. The upper carbon fiber heat shield bolts to the factory lower airbox, allowing the high-flow conical filter to breathe cold air from the factory inlet duct before the radiator. The stainless steel heat shield bolts to the stock intake tube mounting point and to the back of the head, preventing the high temperatures from the exhaust header and turbo from radiating directly at the intake tube. Both heat shields work together to minimize pre-turbo intake air temperature.

4" DIAMETER FOR MAXIMUM PERFORMANCE

034Motorsport engineers identified a serious bottleneck in the factory intake system. The factory, 2.8” turbo inlet size, which necks down even smaller throughout the unit, is by far the largest restriction in the intake system after a performance filter system is installed. Many aftermarket companies, including 034Motorsport, have solved this issue by increasing the turbo inlet diameter, thus warranting an intake that supports the added flow gain. The 4” diameter intake kit is designed to support upgraded 4” turbo inlets that can be used on factory, hybrid, and full frame turbochargers. It has been validated that this intake works with the majority of aftermarket inlet options, but has been optimized to work with the upcoming 034Motorsport 4” turbo inlet.

MINIMIZING UNNECESSARY FILTER SHROUDING

034Motorsport focuses on optimizing every aspect of the intake system across a broad range of variables and compromises. A critical component of a high-flowing performance intake is the ability for air to flow around and into the filter. If the air cannot flow freely around the filter, it will be restricted from getting into it. Many aftermarket kits fit too large of a filter in an enclosure that cannot accommodate its size, thus choking the filter and reducing its overall flow. This often happens when a product is engineered for one variable at the expense of others. 034Motorsport conducted extensive tests and refined its development of the intake design to allow for maximum airflow surrounding the air filter, allowing for optimal airflow to, and through, the filter. The final result is the right size filter in the right size filter housing, creating maximum airflow and performance with OEM level filtering; the ultimate goal of any intake system. Be cautious of any intake that brags only of air filter size without taking into account the detrimental effects of shrouding the filter.

PERFORMANCE AIR FILTER

The 034Motorsport Carbon Fiber Closed-Top Cold Air Intake system houses a high-flow conical air filter with double-layer pleated cotton filtration medium. This air filter design offers increased flow through an enlarged filtration surface, while ensuring superior filtration.

OEM+ FIT & FINISH

034Motorsport carefully selected the carbon fiber weave on the intake tube and upper airbox heat shield to match the factory carbon fiber engine trim found in the Audi TTRS & RS3 2.5 TFSI engine bay. The 034Motorsport Audi TTRS & RS3 4” Cold Air Upper Intake System was designed to fit like a factory part, and mates directly to the turbo inlet pipe and factory lower airbox to provide an OEM+ look.

DYNO-VERIFIED WHEEL HORSEPOWER & TORQUE GAINS

034Motorsport's engineering and development efforts were validated on multiple vehicles using our Mustang AWD Dynamometer to ensure that the 034Motorsport Audi TTRS & RS3 4” Closed-Top Cold Air Upper Intake System provided substantial increases in horsepower and torque on both stock turbo vehicles and ones with upgraded turbo kits alike.

Worth reading to better understand blood sugar, but don’t limit yourself to this one resource
Format: Hardcover
My mother had type 2 diabetes and ultimately died from related kidney failure. For years I have exercised and managed my diet in an effort to avoid a similar fate. I was therefore stunned during a recent doctor's appointment when it was revealed that my hemoglobin A1c was above normal limits. I immediately ordered a continous glucose monitor and was dismayed to see that my blood glucose levels were regularly exceeding what would be considered normal. I am now trying to learn as much as possible about preventing these elevated glucose levels. In my research I was led to Jessie Inchauspe (Glucose Goddess on Instagram) and decided to buy her book, The Glucose Revolution. I will say that the majority of the information in this book is available for free on her Instagram account. However, I like the simplicity of reading through the book rather than scrolling through posts and reels. The author gives a thorough overview of glucose, explaining the different forms and how they act in our bodies. She explains glucose spikes and has a really good explanation of what the hemoglobin A1c test is measuring. She then shares 10 hacks to help lower your blood sugar levels that I feel are relatively easy to incorporate into your eating plan. Some of them, like eating dessert over a sweet snack (eat a sweet food after a meal rather than on its own) were things that I have already been doing intuitively. I do wonder at the description of our stomachs as a sink and the intestine as the pipe below. She claims that when we eat carbs first, they flow uninterrupted into the intestine. Drawing on information from my college nutrition classes many years ago, I seem to remember that chemical digestion begins in your mouth and that because of the churning in your stomach, the food that you eat will all be mixed around and therefore it doesn't really matter what order you eat your foods in. That being said, it's a relatively minor thing to eat a veggie starter and/or eat foods in the described order. I also question the idea that our blood sugar shouldn't rise more than 30 points after eating. If my blood sugar is at 80, that means after eating my glucose level should not be above 110. That is well below the generally accepted rise to 140. I'm not saying that we should always be going to that level, but even a modest rise to 120 would not be accepable according to the standards presented in the book. Of note, the author does not have diabetes or prediabetes and started the Glucose Goddess after working for a company that was developing continuous glucose monitors. Overall, I do think this book is worth reading to better understand blood sugar. I wouldn't limit your knowledge to just this one source of information though. I've been slowly working through articles and videos published on the Nourished by Science website. I really appreciate the perspective offered there. Women entering menoupause might want to investigate the effects of decling estrogen on their blood glucose levels too. The New Menopause by Dr. Mary Claire Haver is a fantastic book on this stage of life.

Glucose Revolution is very healthy and has specific recommendations
Format: Hardcover
This was recommended by an outstanding organization that addresses discomfort and overall health and wellbeing, Pearson and Weary. This gives recommendations to stabilize glucose and flatten curves. There was beneficial discussion of the use of fiber which slows the body's glucose absorption. Comparisons of orange juice (lacks fiber) vs. eating an orange (includes fiber) that does not create a glucose spike. Evaluated sugar as a cause of not feeling well and leading to glucose spikes which can lead to heart disease, type II diabetes and cognitive decline. Glucose spikes also lead to inflammation which is a common source of illnesses: strokes, chronic respiratory disease, heart disease, liver disease, diabetes and obesity. When glucose curves are flattened the body burns fat. The book reviews the short term and long-term effects of glucose spikes. Cornell University which I attended as an undergraduate stated there is a specific order to reduce glucose spies by 73% that includes fiber 1st, protein and fat 2nd, starches and sugars last. Other recommendations: (1) never drink fruit juice as sugar from fruit is missing the fiber "resulting in disastrous blood glucose levels." (2) Breakfast cereals is one of the "worst ways to begin your day as it always creates tremendous glucose spikes." Choose savory breakfast can include yogurt, meat, cream cheese, protein powder, butter, eggs, and seeds. Toast alone increases glucose spikes but added peanut butter or avocado can minimize spike. (3) artificial sweeteners can increase insulin rise and havoc in the gastrointestinal system. (4) fasting has benefits for 8-12 hours. (5) snacking increases obesity. (6) add one tablespoon of apple cider vinegar to a large glass of water which is best 20 minutes before eating. This approach after 3 months led to a loss of 2-4 pounds. Vinegar stimulates mitochondria to burn more fat. (7) exercising after eating can also reduce glucose spike and is beneficial within 70 minutes of food consumption.

READ THIS AND CHANGE YOUR LIFE FOR THE BETTER NOW!!!
33% of Americans are verging on type 2 diabetes and do not know it. This should make you run to get this book! Following Glucose goddess on Instagram and got her book as well. It is easy to read, with fun illustrations by the author. She has truly helped me so much with my insulin resistance and managing my glucose spikes. "Lifestyle optimization" is an essential for everyone. Why wait until you are diagnosed? These hacks are simple, fun, and super easy. Her audiobook is also out now and is read by the author!! Which is awesome. What makes this book even MORE useful though, is if you invest in a continuous glucose monitor (CGM) and have the app. I had the Freestyle Libre sensor. Each sensor lasts 2 weeks on the skin and logs your real-time glucose levels 24/7. Way better than doing the old fashioned painful and wasteful lancet and test strips. Although you can verify your CGM occasionally using the lancet, and see how accurate the CGM is. You can have a CGM prescription written for you if you INSIST at your nurse practitioner's. (NPs are WAY more open to this kind of experimentation and self-monitoring...I got the rebuff from the doctor, HA!) What is so sad is that the healthcare system is so broken that insurance will NOT cover a CGM UNTIL you have full-blown type 2 diabetes and are dependent on exogenous insulin delivery. OR if you are a type 1 diabetic and born without the ability to process glucose. Sad huh? The FDA wants you sick, fat, ugly, and miserable. We are MUCH better desperate customers then...willing and eager to take any pills to solve the problems! Let's not be proactive and encourage the PATIENT to take measures against type 2 diabetes, right? So there are MANY benefits of managing glucose. Fairly effortless weight loss actually. In this book she dives into nutrition science and the biochemistry of different sugars as well. She has so much credibility and science-driven data backed up by her own personal journey as well as many peer-reviewed articles. Thank you Jessie!

Really Good Book & Inspired Me to Take Action
Format: Hardcover
After I finished reading the book, I asked my doctor for a Continuous Glucose Monitor. For two weeks, I reduced my carb & sugar intake & was able to keep my glucose in the "steady" range. Then, I ate an oatmeal cookie without pre-eating any fiber or protein. BIG SPIKE! One cookie sent my glucose soaring. I can't even imagine what happens to my body when I eat 1/2 pound of candy. This book was written in a very understandable way & it inspired me to start tracking my glucose levels. I recommend reading this book. And there is definitely something about seeing the effect on your body when you eat sugar by using a CGM. It's an almost immediate visual telling you that you're inflicting damage on yourself. When you don't see it, you can pretend it's not really happening. When I saw that spike, I imagined my poor body trying to release all that insulin to remove sugar from my blood.
