In your opinion or by facts which filter will flow better a K& N type air filter or a foam filter such as the TPIS kind? Which is better performing?

 

I had a foam filter once, sat on top my Stang's carb, one backfire and it got sucked right in. Though I'm sure it would be different on a TPI.
There's a reason why everyone buys K&N.

 

Have heard nothing but praise for K&N filters over the years - the wire gauze ones where you add the oil. Seem to remember one of the car mags ran various tests with air filters a few years ago : standard paper ones , foam ones and the mesh ones : the mesh ones , infact it was a K&N , came out tops in all respects ie. Longevity , airflow , stopping particles etc etc , I think you get a lifetime guarantee with it as well. The K&N was one of the more expensive ones , which is still the case today , but if I was gonna get an aftermarket airfilter , it would be a K&N - they have a good reputation over here.

 

oh , and I seem to remember it was worth an extra 3 bhp !

 

I ran foam filters on my VW for about a month. They hold water between the foam cells and have a tendency to implode. I've had K&N's on it for 3 years now. Guess which I think is better.

 

K&N would be better than a foam (seat cushion modification?) filter. But then again, a stock air filter element would probably flow more air than 90% of the people on this board need anyways...

 

yeah....i was lucky my car came with K&Ns...otherwise i would have never bought them.....

 

be aware that if you over-oil your k&n filter, there is a good probability that you will damage the MAF sensor (Mass Air Flow). Replacement MAF sensors are not cheap.

 

yup, i once overoiled a filter on my old Integra, and i took the intake hose off one day for some reason, and the inside of it was covered in sticky red oil!!

 

One of the car magazines just had a write-up on this topic. I think it was Car Craft or CHP, but as far as flow and dyno tests, there's hardly any difference between any of them.

 

...yep....just like dirtbike filters.....man for the size of the motor....the filters on DB have more Surface area then Big Block V8....and they are cleaned just like K&Ns and they only go for $20-$25....while K&Ns go for 50?

 

Hey Camaro6spd. You should go for a 350 instead of a 305. Lots more torque than a 305.

 

I know a guy with an import; told me he's got a cold air intake, and we were talking about what a pain it is to clean the filters. He has a filter similar to a K&N, but doesn't use cleaner or oil on it! He just rinsed his with water and put it back on the car. Anyone heard of a filter like this??? I think he's doing it wrong!
