Whats better performance based, a 6637 filter or a replacement type k&n filter

 

The K&N Filter will allow more dust particles into your intake which is not good for the engine. Due to it can score the cylinder walls eventually. Some people have better luck with K&N but as far as the replacement type K&N that definately allows plenty of dust in from the top of the filter housing since it doesn't seat too good.
The 6637 costs about 50 bucks at NAPA and I've read is a Favorable mod.

 

those dust part. will dust ur turbo too. that would be the first thing to go. the 6637 is also oiled, therefore catches more dirt and such. I believe they flow about the same, think i read that the 6637 flows better but im not too sure.

 

I can tell you the 6637 filter is much better for performance, when i bought my truck the guy before put a k&n replacement filter on it, it helped. Just yesterday i put the the 6637 filter on and i noticed a difference, takes off a little better, I will let you know how my truck does on mpg after this weekend.

 

i beleive the k and n has the capability to flow more air but the engine wont use the amount its capable of. the 6637 flows more than enough air for your engine and does 100 times the filtering the k and n does.

 

I really should have researched this a little more before i went and bought my k&n filter about a month ago. I am probably going to buy a 6637 now and install it on my truck. Thanks for the help

 

alot of people claim good luck with the k and n filters but i know i rest easy driving through a dusty construction zone running my 6637

 

6637 wins every time! can't screw it up unless you don't know how to work a hose clamp!

 

Yea. that air box is just trash.

Put the K&N on a shelf and look at it with a sticky note that says "no!"
Think in your head of louis black saying it as well, will make ya giggle everytime you look at it. =)

 

Are you sure about this?, I pretty sure that the 6637 is NONoiled

 

I don't believe it is oiled either. Mine was dry as a bone.

 

It could be oiled, but you can't tell.

They look like they are dry to me though as well.

 

not oiled......

 

ok their not oiled.i was just joking.ha.

 

I knew you were joking!
