K&N 33-2497 Air Filter Product Reviews

I use K&N products on all of my cars. K&N backs up the products with great service.

You will always have customers with the product and service you offer. The enthusiast is always looking for more. More power, more appearance, more compliments. Your filters give two of the three, power and compliments. The driver gets the power and your passengers compliment the performance, not to say anything about the increase in economy if you can keep your foot out of the throttle. This is my third street car that I've K&N'd.

Changing this filter was easy and for my 2.0t, runs even harder now with a lot more air coming in.
