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.

I just got this product yesterday and since putting it in my 1999 ford escort I feel more power out of it the acceleration is better. This product is amazing. The only thing is I wish I could find the cold air intake pipe for my car.

Just put the 57 series intake on my 2001 Chevy Blazer Xtreme and WOW!!! The performance is great and the sound is awesome when you get around 3000 plus RPM or when you're in a strong pull.
Since K&N doesn't make a complete system for my 1990 Mustang GT, just the filter, this is my first real intake with air duct and filter and I'm really impressed.
Thanks K&N for the great products. I also bought a 69 series Typhoon for my wife's 2002 Toyota Celica. Put it on and dang...it is loud!!! Now I see why its called a Typhoon. You got a customer for life.
Thanks K&N.
