K&N Air Filters

Why buy any other brand?

I love everything about my K&N air filter. I wish I knew about them when I first got my car, but even after installing it with over 100K miles on my Civic, I immediately noticed better gas mileage! Just imagine the money I would've save had I installed these when I first bought my car over 10 years ago. Thank you for creating a great product. View more reviews...

K&N 69 Series Typhoon Intake Systems

2004 Honda civic ex

Its the first mod I've done and I like it a lot! Pretty easy to install too, the instructions are a little veige but with a little common sense its pretty easy took 30 mins. It gave me more hp and Mabe 1mpg more, the only thing is the sound it's pretty loud (the intake sucking in the air like a whistle)but gives yur car engin a more aggressive sound. I love the engin sound and the hp gain. View more reviews...
