Performance

Ease Of Installation

I have put K&N in my Toyota trucks & Cars, Audis, Porsches, Lexus, and Jeeps. And I've gotten all my family to do the same. Regardless of the manufacturer, there is always a NOTICEABLE performance gain. Just make sure you don't put too much oil on them when you clean them.

KN in all my cars

K and N Filters

Great job on expediting the right product in a timely fashion. Very easy install. If/when you have specials (specifically oil filters for a 3.2 L Porsche Cayenne) notify me. 

BTW: my onboard computrer suggests I have increased my gas milage by 3 MPG.

5 Star Review

I have an AUDI Q7 3.0TDI that has 9000km, so it is practicly new. I bought an K&N Filter and it is amazing even though in a new car it is difficult to notice the difference by only changing only the air filter, but there are:
       Stock Filter                           K&n Filter

0-100Km/h (in S)         - 8.3 sec              - 7.8 sec
70-120Km/h (in 6 gear) - 14.3s                - 13.9 s
70-120Kn/h (in D)          - 8 s                  - 7.1 s
100km                  - ~13.5L(diesel)       - ~12L(diesel)

I have now a quicker response on the gas pedal so I just think that's great and considering that it is a lifetime filter it is worth the money, because you will get that money back and even a good part of the diesel that you buy. 
Thanks K&N.

I purchased 2 of your air filters for my 2004 Porsche Cayenne S. All I can say is WOW. The gas milage has gone up to around 16 miles per gallon now as opposed to the 14 I was getting before. I would estimate an added 10 more HP. The car was powerful before but now it feels like it has a turbo. The engine sounds more powerful, and runs smoother. I highly recommend these filters to anyone with a high performance car, or in fact any car. I have recommended these air filters to my friend who has a BMW. I hope her results are as noticeable as mine. A+++++ product. The car hurled itself to 140 MPH in no time.

2004 Porsche Cayenne with K&N
No words can describe the increased performance increase on my 2004 Cayenne S after installing the K&N (replacement filter & not even an intake system, because K&N does not offer one at this time)!  My stock Cayenne was a powerful beast to begin with, but what the heck, I decided & but skeptical to test out to see if the K&Ns would even make me recognize even a bit of increase I can really feel.  I'm talkin' FEEL & not statistics & I can feel the increased performance at overall conditions of my driving.  I don't understand why K&N does not come as OEM of the Cayenne & all other automakers out there.  This is the most effective & worthy modification I've done to my Baby & not avoiding a factory warranty?!?! & not to mention, COST-EFFECTIVE for the value of the performance tweak you can achieve!! Truly feels like I now have Cayenne turbo & saved $$$$$! $^~^.Highly praise it & recommend K&N for any autos in this planet.  

Thanks K&N!!~!!

I have been using K&N filters for over ten years. Never disappointed with the performance, always nice to be able to clean it not be throwing something else in the landfill. Looking forward to see how this helps with my new to me VW Touareg TDI.

Great Air Filter

This was one of my many purchases from K&N . It's pure quality.  I highly recommend this brand. Very satisfied every time.  Keep up with the great work team.

K&N filters

I needed an air filter for my Audi Q7 Diesel so I thought of K&N.  I ordered the filter.  It was a perfect fit as well as improved performance and this is a washable, life time filter.  Win, win.

Immediately noticed a difference with throttle response and power increase. Thank you for making for my wife's suv, dropped right in.

Noticeable

The goods have been received and installed, and the use effect is good. I hope you can refund me the money for the delivery of the wrong goods as soon as possible according to the customer service
