What brand of air filter do ya'll like?

[my first gmc]

Ok, in the chevy crowd, there a popular mod to make a "homemade air intake". And a lot of people are getting better mileage, I'm guessing because these intake don't have boxes so they can intake warm engine compartment air and they're way lest restrictive. Anyways, a lot of people are saying that the K&N filters can hurt your mileage because of the oil you have to put on them. So I'm looking for a filter that doesn't need to be oiled, like an AEM. Do ya'll know of any other brand that ya'll prefer?

I have a turbo flow foam air filter and I love it, it has over 150,000 miles on it and still works like new, every year or two I wash it with soap and water, dry it and re-oil it with high tack air filter oil, my car also has 210psi compression on all 4 cylinders with 270,000 miles and the original non rebuilt engine and I give the foam air filter credit for that because they tend to stop nearly all the dirt, that is why I tossed out all my K&N filters is the large amounts of grit they let in to the engine are a pain to clean out and cause alot of wear as it seeps past the rings and in to your oil.

Amsoil used to sell a line of foam air filters now they just sell micro fiber air filters that they claim are just as good.

I use stock paper air filters on my cars. Period.

"there a popular mod to make a "homemade air intake". And a lot of people are getting better mileage"... yeah right.

The stock style paper ones, whatever one happens to be on sale, are what my stuff gets. Although, really, my stuff is on a 80,000 mile change out schedule. Not that they need to be changed then, but just out of guilt.

P.S. Almost all my vehicles have over 100,000M... one has 270,000M... so the evidence points to effective filtering right?

I use Wix air filters on recommendation from a member of another forum.

Same here. I did try a K&N once, and noticed a bit snappier acceleration, but no difference in mpg, so I went back to paper because they appear to filter better. Only the Celeb has about 180k, everything else in my driveway has around 250k, so paper ones must work just fine. Also I could buy paper filters for the life of the car for the price of the K&N, and then you've still got to get the re-oiling kit.

Ok, thanks guys. I would keep a paper filter, but with the filter not being in an airbox i would think it would get dirty really quick and with stock replacements being $20 a washable filter would be a better option. I think what I'm going to do is set it up with my stock filter (because besides the filter, it's $10 of parts) and if i see any gains, get a new reusable filter.

This is what it would look like after.

RE K&N: More hassle, less effective than paper and NO MPG Gain.

If you have a MAF and over oil the K&N filter, the MAF will need frequent cleaning.
If you under oil the K&N filter, it's next to worthless.
When you clean the filter (likely required more often than K&N suggests), you must let it throughly dry (several hours) before re-oiling and reinstalling.

I said i didn't want a k&n because of the oil. I was looking into a aem because it doesn't need to be oiled.

Wix or Baldwin standard filters.
