The ALTA Five-Ply Silicone Elbow included with our intake, is rated for 200psi, and 400 degrees. Like other ALTA products this part is over built to ensure a lifetime of trouble free use. This is one of the key features to our intake as the bend provides the proper MAF (Mass Air Flow) sensor reading and ensures no Check Engine Lights. With an ALTA intake system your car will make a throaty, deep tone on throttle that is undeniably modified. You will be able to hear your turbo spooling and hear your blow off valve every time it opens. Even the stock one.
The ALTA Turbo MINI Air Box was designed with light weight aluminum. This provides a stiff, strong, and corrosion proof shroud for the ALTA high flow foam filter and a connection point for the fresh air tube. With a black wrinkle finish powder coat is applied to keep things looking clean and finished for that show appearance under the hood.
ALTA's intake is designed to remove the OEM hood scoop plug/screen. During initial testing we found removing this provides consistent ambient temps to the filter. While it's not a traditional "Cold Air Intake" where the filter is located in a fender well, the ALTA Cold Air Intake is just as good as it still gets a constant flow of ambient cold air. This is just one of the reasons why or intake has dyno proven HP! NOTE: On early production cars the screen is decorative only and is sealed off completely. You must remove it for best performance. On later models the scoop screen is mostly open and can be left in place.
ALTA Cold Air Intake has proven a 10-12 WHP and torque gain many times over.
The ALTA Cold Air Intake System for R55/R56/R57 Cooper/Clubman S & JCW is available in black or red texture powder coating.

Good quality!
Size: 9.3" x 9.7" x 1.8"
This cabin air filter is seriously a game-changer for my car's interior air quality. I was getting tired of that stale, dusty smell every time I turned on the AC. Swapping it out was surprisingly easy, and the difference was noticeable almost immediately. It really does trap all those tiny particles, like pollen and dust, that used to make my allergies flare up. Now, the air inside my vehicle feels so much fresher and cleaner. I've been recommending this brand to all my friends who are looking for a reliable filter. It's definitely worth the investment for a more comfortable driving experience. Seriously, if you're on the fence, just go for it!

Noticeable upgrade in air quality and a seamless installation
Size: 9.3" x 9.7" x 1.8"
I'm generally skeptical of the "HEPA" marketing for automotive filters, but after installing this in my Honda, the reduction in exterior odors—especially exhaust and pollen—is actually significant. The construction feels far more robust than the flimsy OEM paper filters I’ve used in the past; the pleats are dense and well-reinforced, which gives me more confidence in its filtration efficacy over a 12,000-mile interval.
Installation was straightforward and took less than five minutes. It’s a precision fit with no gaps around the edges, ensuring that all intake air is actually being routed through the media rather than bypassing it. One thing to note is that you might notice a very slight decrease in max fan velocity due to the increased density of the HEPA material, but the tradeoff for cleaner air is well worth it in my opinion. If you live in an area with high pollution or suffer from seasonal allergies, this is a legitimate quality-of-life improvement for your daily commute.

Exact fit!
Size: 9.3" x 9.7" x 1.8"
Was a great replacement for OE on my 2012 Honda Accord. It was the exact same size as the previous filter and has no strange smells or odors. Very easy to install behind the glove box and looks great!

Great Filter, Good Quality!
Size: 9.3" x 9.7" x 1.8"
The beauty of this filter is that it comes with very clear instructions on what to do. Not a lot of manufacturers. Give clear instructions. I got this for a 2007 MDX.
The packaging of the product itself was well done by Bosch. Installation was a breeze and as soon as I turned on the air conditioning post installation, I could tell the very clear difference.
Plus, I also got an opportunity to look at the old filter which was filled with the usual culprits and debris.
The initial airflow did have a mild smell of kerosene or like fuel. But this could also be because of the filter component itself needing to be vented out. I would recommend keeping the filter out for about 30 to 60 minutes before installation.
Once installed, however, the improvement in air quality was very evident. The fit was very good as well.
Highly recommend this. Very high quality.
