Any evidence for for the dis on K& N oiled element? I see the link posted above to tests showns K N as "good" not "very poor" like the HKS green thing.I think you should buy either a stock pleated paper element, or even better, an Amsoil drop-in.
K&N is very poor at filtering the fine particulates that cause wear.
Are you serious? The infamous "green mushroom of death" is the one type of filter that is known to have terrible filtering protection. Only good for keeping gravel out.I think you should buy this filter.. it will look Bad Ass and preform well..
If you don't already belong, join BITOG (Bob Is The Oil Guy), and search "Cone Filters". Plus, any 4x4 forum will likely say the same thing, under dusty conditions they (K&N) don't filter well.Any evidence for for the dis on K& N oiled element?

+1 here for Nick's advice that it really doesn't get you anywhere to change out the stock box on a BPU car.
I'm with you -- I question whether there was any restriction for BPU in the stock air box.It was the Jarvis Steve. I've always wondered about that, since I never saw *any* trap speed increase with the Max Air box.
I ended up taking it out and going back to stock for that last couple of years before going single. I don't mind giving up maybe 10 rwhp for much better filtration. although now that Amsoil is using the nanofiber technology from Donaldson you can buy a cone filter that both flows and filters extemely well. Using that type of cone with the Max Air would be the way to go, IMO.
