i have a 2000 camaro and i want to know if the filter actualy improves fuel effiency and increases horsepower. And how much horse Power ?

 

No, you are not going to get big gains by using this filter. Now I have used the same K&N's for the last ten years with only a once year cleaning and oiling. That is what I like over the standard paper filters they are good and same money. The 1 to 2 HP gains are a bonus.

 

K&N filter does nothing for performance or mileage, unless the filter you are replacing happens to be dirty & clogged.

 

Your fuel Effiency should go up a little bit, right? I mean, more air will get in your intake box cause K&N 'says' you get, er at least I get 441 CFM compared to 319 CFM with a regular aftermarket paper air filter. Soooo...You get more air and more air means better power gains. I read somewhere that even a CAI doesnt do that much compared to your regular air box. If you want a lotta air then get or make a ram air induction. Pretty simple. Im making one now out of some plastic sheets I bought from Home Depot and I'm soldering them together. I dunno if it will be able to withstand 50+ MPH winds but hey...Ill try it

 

Just because the air filter passes more air, it really does not mean that the engine can use it. In a stock filters are sized big enough to feed a stock engine all the air it can use, however the air plumbing beteween the air filter and the throttle valve is pretty well restricted, just to make sure when the same engine is used in a Vette, it makes more power. Instaed of changing to a different filter element, get a cold air intake which provides less restrictive plumbing and a denser air charge.
