K&N or 6637 filter for DIY???????

[taylorking]

so the local parts house can get me the 6637 filter to use with my DIY intake for $40. I was just lookin on eBay and there is this filter. Its a K&N with 4" inlet. Would this flow better??? I'm thinking i should get it since its the same price as the 6637 and it's washable.

Any more recommendations on the best filter to use for around $40???

IMO the K&N doesnt filter well enough and is a gamble on harming your engine....

i would do the 6637 if i was you

+1 for the 6637. You won't believe how HUGE this filter is until you actually see it.

I've always heard bad things about K&N's on diesel applications.

Also buy it from fleetfilter lots cheaper then nappa

yeah the 6637 is 25 from fleetfilter. Definitely stay awan from k&N I made that mistake and I just bought an amsoil filter to replace it. Much bigger and flows a lot better

I used to have the K&N, but decided I would try the NAPA based on what ORG users were saying. I've been running it for 2 months and have already noticed that it's cleaner under the hood, not near as much dusty oil residue. The filter is also a hellofva lot bigger As far as performance goes, I could not tell any differ.

wow ok i'll definitely stick with the 6637 filter. Seems like you guys know what you're talking about.

thanks!

20 bucks is a GOOD price. I ordered a Baldwin PA2818 for $46 with shipping. Won't do it again. Go with the 6637.

Wow, my NAPA parts store charged me 51.00 +tx for 6637. I really like it though talk about opening up the air flow.
