k&N filter vs. paper filter
k&N filter vs. paper filter hey, i was wondering if a k&N air filter will actually give me any hp over a cheap autozone paper filter? is it worth $60? and will a p&p throttle body give me any good hp gains?
thanks
thanks
supposedly running no filter at all vs air filter is a 1-3hp difference so i would doubt the K&N would do anything at all power-wise. the real benefit is that you can clean it so you never have to replace it. there are also debates about whether they actually filter as well as paper and whether the oil used to clean them messes up the MAF but i don't know if there's any truth to either of those.
you'll feel a difference in throttle response with a ported tb and pick up a few hp. if you're handy with a dremel just DIY and you'll save yourself some money

I like the K/N because you can wash them so you will get your money back over time. But as far as a power gain not realy. A P/P throttle body is worth a few HP. If your looking for some more power... Might be time for a cam.
The K&N is NOT worth it. I just took mine out and relplaced it with a Fram paper filter. There are threads on here about paper filters out filtering a k&n and how the oil on the k&n filter can and will come off and clog your maf but I dont have them handy right now. Also the guy that tunes my car did a dyno test with a k&n, stock paper filter, and no filter at all and they all made the same power and he has a 485HP head and cam car. Another thing that turns me away from a k&n is they are about $60. A paper filter (Fram in my case) is about $10. You are recomended to replace a paper filter every 15000 miles. I put about 5000 miles a year on my car. That being said, It would take me 12 years if im correct to start saving money with the washable k&n
. Just my 2cents
. Just my 2cents I had one becuase it was like an extra $20 bucks or something when I bought my lid. That being said it isn't even on there anymore. I just run paper frams and replace them like 5k miles. I have a the free ram air mod done and it makes the filters dirty. Even thought I highly doubt the dirt I am seeing on the Frams is restricting them in anyway I still replace them becuase they cheap. My K&N made my MAF all oily and I never cleaned it or oiled it. All facotry oiling.

Ported tb makes a huge difference in throttle response, but I didn't see anything at the track from it. The throttle response alone makes it well worth it, IMO.
i also wondered the same thing. i had my K & N filter for a good year or 2.. i ended up just throwing it away and picking up a brand new fram air filter. i doubt that i would even notice a difference.
i decided to port it last night, took quite a bit of material off and smoothed it out. didnt get a chance to really get on it cause it started raining but now its done and didnt cost me anything
Ive done a comparison on k+n v.s. paper filter v.s. no filter. on a dyno and the numbers were very different. i gained 17 hp with a k+n filter compared to a paper filter. and it was about the same with no filter on it but obviously you all kow not to do that. i run one in my car and have since i got it, making my own pulls on our dyno showed me all the difference i needed to see. id go with a k+n all the way.
