Air Filter Testing
#126
I increased my mileage with my airbox setup, and def felt a vast improvement over the sad ass Injen intake I used to have.
I also had the AEM intake. It is the same thing as running a modifed airbox. Just much more expensive.
I felt more power while running the factory ac delco than the K&N drop in filter. My car made 299.45whp with the factory filter.

All you might gain is some sound, because the filter would be 100% exposed.

Maybe ill just drive a little longer and wait until the weather is a little better to make a proper judgment on the fuel economy, lol. Not worried about the sound as much as having a clean engine and spend as little on gas as possible!

I changed back to the stock air filter to protect my engine and it actually provided more get up and go than the K&N drop in (believe it or not). More than likely because it is a much larger filter.

I can care less about gas mileage, lol. Even though my car gets 22 on avg around town with a heavy foot.

The last job I had was less than 2 km from my place. I cared a lot less about mpg back then

I've known that the K&N's don't filter the fine particles for years. On one of my Grand Nationals back in the early 90's I had a cold air kit with a scoop mounted right under the bumper. I had one of the K&N cone filters that was prob 8-9" long and after maybe 15k miles I took it off to put on a longer one after upgrading the turbo. I stuck my finger inside the filter and ran it around the inside step/ledge where the filter is the largest and this area obviously had some filter oil finely misted over it after all the miles and there was a real fine grit all around the lip area. I could feel it on my fingers, it wasn't as coarse as sand but more like a flour/fine consistency. You can hold a brand new K&N up to the sunlight and look through it and see many small areas of direct white light, thats nothing but small/minute holes in the media. Pretty much nothing filters as well as the stock filter material. Heck, the K&N prob filters better as all the small/minute holes start getting clogged up....at the cost of airflow. Too bad someone couldn't come up with a different type of airbox that used one of the largest style flat filters that GM has, or use 2 large GM filters on the sides of the airbox etc..
