Customer Feedback

I've have never been disappointed by the quality and value of a K&N filter. I've purchased one for every vehicle I've purchased in the last 25 years. I keep my cars to 200k+, Motorcycles to 80k+, and all sold running well. K&N air filters lowers cost of maintenance, boost performance and efficiency of the vehicle. Acura Legend 290K Toyota Celica 287k, Honda GL1100 91K, Passat TDI 240K, Honda ST1100 89K and Currently Yamaha FJR1300 43K & Toyota Corolla 88K.

No issues out of the box; filter fit right in place within the factory Honda box. I can tell an improvement in power when I step on the gas, which is needed out of a 4 cyl engine. Have used K&N Filters in my V8 truck with the same increased response. Great product, no complaints

The install took a little longer than I was expecting but going from a Honda to a Lexus IS quite different and I'd use the same method for install if I had to do it again. Kinda bummed out that the cleaning kit did not come with the intake for the price I paid for it, seems like they could have thrown that in. The intake itself has increased a noticeable amount of torque in acceleration . It's a low growl under 2500-3000 rpms but once u hit about 40 mph u can tell the difference and a bit of growling sound that will give your v6 a new place in people's hearts cause they definitely stop and look, it's priceless on the freeway above 60 mph when you have a distance to travel. I would recommend this product to anyone, Thanks K&N!
