Does anyone have any experience using a K and N airfilter. Does it really improve performance and gas milage?

 

Might give you one or two more hp if that,gas mileage will not increase much at all.

 

herbvdh,

I have one in my car. Added a few horsepower maybe 5 or so but I mainly got it for the fact that I didn't need to keep spending 20 bucks in replacements. Not a noticeable power difference but I liked the fact that It was reuseable.

Cost me $56. If you decide to go with it the model number is E-2606.

Good luck

 

I added one recently. I can't say about the power addition, as if it there is one it's unoticable.

It does give the engine a little more growl though.

Here is a link to some of my installation pics.
