Yeah, 25 does seem a little excessive......but maybe thats HP at the crank? Not at the wheel? I don't know, thats just what it says on the ad. And you know, ads never lie..........or do they? lol

 

Ok, I looked into it a little. K&N claims it adds like 25.8 horsepower at 4300 rpm, they even have a dyno chart. Check it out. You can access it from their site or from Racing Beat's site, cause they sell them. Btw the K&N has a powder-coated heat-shield to prevent water and debris from getin in the filter. Check it out......
