Aftermarket Air Filters Overrated??

I think it probly does flow a little better (not much) but what I like about the K&N is once its dirty you just clean it. FWIT I have had K&N on all of my cars and ran SSRA on my last 2 cars. If anyone is prone to sucking in dirt its me with the SSRA. If these filters do let dirt through its news to me. You should see how much sand ends up sitting in my airbox after a few months.

It is a known fact the k&n filters do flow more but they do it by using bigger holes in the filter. The tiny more amount of air they let flow through isnt enough to increase as much hp as they claim. I used k&n in my car for a while and the oil used in the filter used to build up on my maf after a while and start causing problems and the filter wasnt over oiled as it would take several hundred miles for it to happen. If your going to spend money on a high dollar filter like that get an amsoil or another filter that doesnt use oil. the amsoil one flows better than an k&n lets less stuff through and can be cleaned out with compressed air.

k&n is a great filter along with the green air filter which is a cotton based filter. After awhile you have to clean these filters and it helps a lot better then having all the oils and sh** getting through and all over the MAF. clean the filter at least every 2 months if ur a heavy driver, you will see it then work at its best

Way, way back when, I measured some air filter pressure
drops and they were all way, way less than the screened
MAF or the stock airflid. Purolator paper filter is what I
prefer.

I did the same flowed a k&n filter vs a paper fram and they gave the same pressure drop...the paper might even have been a hair better iirc...

could run no filter if u want all the air flow possible or at least at the track. i know that on my z28 i ran a 12.9 @ 106 with a k&n. pulled it out and ran no filter and dropped to 12.7 @ 108. put the filter back in and slowed back down to 12.9. i know that this is a filter VS filter argument/comparsion, but heres just some input on what airflow can do

Nice for a short run to go without a filter ....but that's really pointless. So your car runs faster without a filter, you gonna always drive the car without a filter? Unless you are then the times you get without one are pretty useless.
Filters purpose is to filter dirt out of the air. K&N and other gauze filters do a poorer job at this than paper filters. The oil that's supposed to make up for their sparser media doesn't do nearly as good of a job as a regular paper filter. And when compared to a clean or somewhat clean paper filter, offers little to no benefit in flowrate. Additionally, they often cost 4x what a paper filter costs and most paper filters will last you a year. So monetarily it makes little to no sense either.
At least when it comes to your standard air box type filter, sticking with paper is smarter than not.

The only time the car see any other type of road beside the strip is on a trailer going to the strip. I don't drive it anywhere else so I don't have to fiddle with it everytime I go. After a out 50 to 75 runs I had very little dirt in the intake. Say what u want but I know quite a few ppl would do the same and it works for them

I think K&N type filters have their place. In situations like thegroup's car where you don't drive it anywhere but the track and you only need something to prevent stones and such from entering the intake. So it's not really bashing. Nobody should expect their product to be the right choice in 100% of applications, or even a majority.

you had no gains because they were single digit (if any) gains... which is hard to measure in your situation at the race track.
