K&N.

Came with the car.

Its getting dirty, I'll probably go with a fram or stock replacement when I'm done with this one.

anyone that uses a oil based filter is going to want to clean your MAF every so often to get the oil off of the sensors. i was pinging bad before i cleaned mine. now i have none. also be careful putting a fresh re-charged filter back in too soon before it dries.

i first had a k&n, switched to a holly due to fitment issues and now run a fram

thanks for that info.

I run a purrolator too, it replaced my K&N

I wanted the fram, as i heard it was good, but the local parts store didn't have it, so i bought the purolator, glad to know it was a good buy

Hey run what makes you happy. I mean run what you believe in, there is way too many different belief's on what is better/worse... I'm sure someone has dynoed their car with a K&N vs let's say a Puralator, Fram, Wix paper filter.

Does anyone have any dyno info? I won't change mine regardless but atleast this post would benefit from some dyno numbers, Fred

I will be throwing out my K & N and getting the Holley. I heard they fit better and IMO look better.

Paper filters will stop more dirt that the K&N...and ya dont have screw around and clean and oil that darn thing...too much oil and it screws up MAF...I change mine every 6000 miles I get a little more dirt with the FTRA..so I change more often..

i use electrical contact cleaner and spray it on. just be careful with the sensor wires. its amazing how clean they are after you do it the first time.

Do you spray the wires directly to clean them (just want to be sure)?

Yep, I also had a paper Donaldson that was stock in my '02 Hawk..... Then I upgraded to the oiled Donaldson Blackwing filter that they make for the F-body. The quality on it is top-notch, it flowed better than the Donaldson paper (homebrew manometer), and no tiny pinholes like the K&N has!

i run a k&n in my 400ex which i have about 10k in so far. ive had that thing packed so full of dirt i actually had to scrape it out with a SCREWDRIVER a few times before cleaning. i run with no airbox lid so whatever gets thrown on it gets stuck. the inside of that filter has been spotless since day 1. every dirt track car ive ever wrenched on has had a k&n including the sprint car i did most of my wrenching on. i've seen them perform and i think ill keep mine. i will need a new gasket for it when i order my new lid though ... think i might use some badass weather stripping.
