Knappster Posted April 29, 2009 Share Posted April 29, 2009 K & N makes on for about $60-70. I noticed better performance on my GX by installing it. Quote Link to comment Share on other sites More sharing options...
BlackBubble Posted April 30, 2009 Share Posted April 30, 2009 Does the K&N air filter affect gas mileage at all? Quote Link to comment Share on other sites More sharing options...
The G Man Posted April 30, 2009 Share Posted April 30, 2009 K&N, like all the orher so call performance drop in panel filter does nothing for horse power or gas mileage. About the only difference is that the engine will feel quicker due to the new filter and it is louder. To increase horsepower noticebly, you need a K&N cold air intake kit.

Knappster Posted April 30, 2009 Share Posted April 30, 2009 Yeah, it's not a huge difference, but you can feel the engine "breathe" better. If you want to see some big differences, yes, the cold air intake is the way to go. Quote Link to comment Share on other sites More sharing options...
