For the past 18 years I have used K&N air filters in all my vehicles. Currently, I own a 2010 Acura RL in which I installed the correct corresponding K&N filter two years ago. Recently I purchased a 2010 pre-owned Lexus LS 460 and on November 20, 2013 I had two K&N filters intalled in this vehicle. As with past vehicles, I am looking forward to better performance and improved gas mileage in these two vehicles. SGFrederick

These filters kick butt. I put an air filter (not CAI, just the drop-in type) in our Mazda MPV (a van) and it actually has the Zoom-Zoom that silly Mazda tagline promoted! Nice boost of HP!

Since that one did so well, I decided to put one in my Acura RL. The car already had power, but it seemed to lack the smooth acceleration from low-end to high-end I expected when it got broken in. I removed the filter, dropped the K&N filter in, and it now has the smooth power I had expected. Not a big HP jump, but the smoothness is much improved.

Car manufacturers should use them!

I just installed the K & N system on my 2004 4.6 Ford Explorer. My gas mileage has improves around town by 2 mpg & 4 mpg on highway. The throttle response is amazing. I can tell HP has improved. I have a performance rear end so it really moves for an SUV. Next step s to get filter for my 1997 Acura 3.5 RL with only 49,000 miles.
Just a great product.
