The world´s first model adapted air filter kit for Porsche 992 Turbo, Turbo S!Background
Upon launching the 992 generation Porsche had abandoned intercooler and air filter layout that has been used in the previous 996, 997 and 991 generations. Each car model comes with its own challenges and preconditions. While the principle is the same as ever, the layout of the intercooler system is something entirely new on this platform compared to previous versions, and this also affects the air intake. Contrary to earlier versions, the 992 no longer has a common, united air filter for both turbo chargers. The air filters themselves and their housings are located inside each rear fender. The air intake feeds for the filters are located in the decklid shared with the intercooler ambient duct and the rear fenders scoops. Looking at it from the side, this solution has more thought to it, but there´s absolutely room for improvement we give you the do88 intake kit!
Key figures
- More air to your engine, less backpressure and better airflow! Airflow at 0,175 bar / 2,54 psi pressure drop: 1356-1632 CFM (1228 CFM), 10-33 % higher (depending on version)! See diagram below.
- 3D-freeform designed air filter box made in CAD environment.
- Vacuum infused, prepreg carbon for best finish and fitment.
- Fits towards OE or do88 inlet hoses (66 mm or 80 mm connection).
- Washable BMC cone filters with improved airflow. We recommend following the BMC regeneration procedure every 20,000 25,000 kms. See separate item.
The efficiency of a turbo charged engine is under direct influence of the inlet air temperature (IAT) and the backpressure in the system. A crucial aspect, yet often overlooked, is having sufficient airflow before the compressor to avoid surge. Less vacuum and colder air enables the turbo to produce a larger mass which in the end means more air to the intake summing up, this means noticeable power gains. There are great power wins to be earned with a good induction system! Throughout our years in this business, with countless hours of evaluation and development, we have seen the coherent connection in between IAT, sufficient airflow to the compressor, and the impact this has on the output. With this knowledge in our pocket, it was clear to us already from the beginning that we wanted to create a closed system that is not affected by the surrounding temperature at the same extent as an open air filter is. We also saw the potential of an improvement beyond what a model adapted panel filter provide.
The finished product
We started the development by 3D-scanning the entire designated area on the car. This allowed us to work in a sensible manner, with the products in our CAD-environment using SolidWorks. The entire air filter system is optimized for airflow and radiuses and angles are reworked many times to achieve the best result! The finished product is verified with both Computer Flow Dynamics (CFD) as well with our Superflow SF1020 flowbench. All efforts are made to offer real and trustworthy data for you as a customer.
The do88 air intake kit is made from vacuum infused, prepreg carbon fiber of the finest quality. To boost the airflow, the kit really takes advantage of the full space provided within the car´s structure. The carbon housings are made to accommodate a big, cone filter from renowned BMC, featuring their finest filter media at hand. The do88 intake kit replaces the entire OE air filter box and is a true performance upgrade!
This kit contains all you need to mount this on a Turbo or Turbo S. It comes in three different versions:
- do88 intake kit alone with 66mm connections towards OE inlet hoses.
- do88 intake kit with 66mm connections and do88 66mm inlet hoses.
- do88 intake system with 80mm connections and 80mm inlet hoses.
Please consider this when/if further modifications are done on the vehicle.
We are very proud of the performance upgrade this kit brings especially on tuned cars demanding more oxygen, but an otherwise strictly unmodified car will also see improvements from the better airflow!
Fits:
Porsche 911 (992)

Note, choose:
1. do88 intake kit alone with 66mm connections towards OE inlet hoses.

A clear and concise book
Format: Hardcover
Fascinating book. Berntsen provides some interesting insights and recommendations on how we should fix problems at the CIA and in the national security apparatus. At a time when most critics want to destroy the Agency, Berntsen provides some plain spoken sanity. Human Intelligence, Counterterrorism and National Leadership needs to be read by anyone entering into defense, foreign affairs or intelligence - and anyone else with an interest in how the CIA works.
It is a fast and enjoyable read.

Skimming the Surface
Format: Hardcover
The essence of this book is to succinctly explain the role of CIA's National Clandestine Service (Directorate of Operations) in formulating and more importantly executing a coherent counter-terrorism strategy. Gary Berntsen is a retired CIA intelligence officer (clandestine service) with an impressive record of field assignments to his credit. He also clearly knows the ways of Washington D.C. in that this book is designed for those suffering from attention deficit disorder. While he raises several interesting point in the book, he also reveals an astonishing narrowness of view and tendency to reduce everything to its simplest terms.
In his introductory `background' chapter Berntsen makes the dubious claim that the collection of intelligence from human sources (HUMINT) is the "primary mission of CIA." Apparently he is unaware that CIA was originally founded to produce all source finished intelligence and that the National Intelligence Council (NIC), until recently under CIA, was the final word in the U.S. Intelligence System. Nothing reveals the sorry state of CIA's Directorate of Intelligence better than this claim. In the same manner Berntsen is apparently oblivious to the availability and uses of intelligence collected by technical means. To his credit he does recognize that the best intelligence is more often available from open (non-classified) sources than from secret sources. Yet he neither expands nor follows up this observation.
Berntsen more or less follows this pattern through out this book. For example he provides a brief discussion of the traditional Islamic Banking System called Hawalla, but is apparently unaware that the system is based on a recognized credit not cash and that money does not move across international borders. The system is widely trusted and is widely used by Muslim expatriates in the West and Saudi Arabia to send money home. For this reason Hawalla credit transfers providing money to terrorists are easily lost in a world wide mass of transactions. Yet it is possible to track Hawalla transactions and it has been done without "intensive manpower" allocations.
Berntsen deserves a good deal of respect and credit for his obvious service to the U. S. and his dedication to the cause of clandestine intelligence operations and its hand maiden covert operations. Yet this book is a terminally superficial and ill-considered work by someone who not only should know better, but could have produced a first rate `practical guide' to a counter-terrorism strategy.

Excellent Overview on Counterterrorism
Format: Hardcover
What really sets this book apart from the rest of books on the subject is that it illustrates positive solutions to the problems. It is also a very entertaining and fun read. I would highly recommend this book to anyone concerned over current events and terrorism in our time.
