I bought a performance air filter a few months ago, is it just a waste of money?
1/. Performance - I have not noticed any increase in BHP
2/. Eye candy - Once it is installed you can’t see it
3/. Value for money - It lasts a long time but costs 3 to 4 times the price of a stock filter
4/. Servicing cost - The cleaning kit costs almost as much as a stock replacement filter
5/. Servicing time - It takes longer to clean than just replace

 

There is no point really. You can buy a clear lid from MTI and then you would be able to see the filter but who cares?

I am pretty sure pyschocabbage tested his car and actually lost some power with the performance filter installed.

 

everyone who throws on a lid and a K&N feels the difference....and they've been dyno proven to make power...and more importantly they're a starting block for the other mods you make to your car....the motor needs to breath and when you start making real power you need to get more air in and more air out....the motor is just a pump.

 

wasnt there a very long and involved thread about how performance filters do not really offer any benefits over a stock paper replacement?

 

Yeah, it was a major long and inconclusive thread. You already have one, so relax.

 

I put in a lid and K&N, didn't notice a difference but it really cleans up under the hood. I was going to switch back to my paper filter, but i opened up the lid and the K&N was pretty clean, and the screened MAF didn't have anything on it like it did when i had the paper filter, so i just left it alone.

I do have a slight whistle tho. Not sure if that's from the lid or the AIR tube.

 

I threw in a K&N and defiantly noticed more midrange pull and throttle response...

 

you don't think that was because of putting in a new filter? When i changed my original (never changed in 36k miles ) paper filter with a new one, I definitely noticed a difference in throttle responce.

From that to the lid and clean K&N, i can't say i noticed anything. 10hp maybe, but unless you have motion sickness, you won't notice a difference.

 

No,the old paper one was practicly like new,as a matter of fact,I even saved it just incase...It was thrown in when I got a tune up done like 2 weeks before i put in the K&N.


EDIT- Forgot to mention,for Fathers day I bought my pop a Fram "airhog" for his '03 Eclipse...He did very well mention that he did notice more pickup and smoother and stronger acceleration.

 

Nope. I tried a Fram, K&N and no filter on the dyno and there was no difference. I kept the K&N for a while anyway, until I noticed some grit up by my MAF, which never happened with a Fram. Needless to say, I tossed the K&N... There is no way you could "feel" an increase of 10rwhp (which no filter will give you) on a 300rwhp car anyway...

 

actually you can notice the difference....its called throttle response....ive got a TA and had a lid and filter....then when i put the Ram Air airbox on i noticed a HUGE pickup in throttle response that night.

 

they feel a gain from the LID not the FILTER.. I have dyno tested the FILTER ALONE , both with and without a LID and shown it actually HURTS performance. There were over 40 pulls done and on different days. The second series of tests was after the car had traveled from Houston to North Carolina and back with the filter to ensure the computer was well used to it..

The POINT of an aftermarket filter is to get you to waste your money..

 

i don't know. I felt no gain from either.

 

All cold air kits come with high flow cotton K&N type filters! They are proven to make power...Now all of a sudden Lids are also fake power adders??? What about catbacks?? They dont add any power either?

Losing horsepower by adding a lesser restrictive air filter? WTF?

 

I never said lids don't add power. I just think that if you can "feel" 10hp added to a 300hp car, it's wishful thinking. By the way, the filter does not make the intake. a paper filter is just as good as a K&N. the reason you don't see a paper filter on an external CAI is because you can't wash them.
