Which is the best? BHAF or K&N factory replacement or the AFE stage 1.

 

BHAF. It looks awesome under the hood and it will surprise your buddies when you show them how big it is.

 

Scotty II .......................

 

doesnt the scotty use an oiled filter like the k/n is ?? if so why is there no prob with over oiling the filter in the scotty ?? not knocking it, just curious is all. scott

 

Of the ones you mentioned, Bhaf by far. K&n are great for gassers I would never put one on my cummins. The only aftermarket Air filter system I would even consider is the Scotty. Afe and all the others are way overpriced in my opinion. Think about it, you are paying 250 bucks for a plastic box and some tubes and crap, and I dont think they function as well as the Bhaf that is like 40 bucks. I think the bhaf is the best overall option, unless of course, you opt for the Scotty.

Good Luck with whatever you decide.

 

Better for what? - if your truck is stock you don't need any of them, but a cleanable lifetime filter will save you money in the long run. An intake kit is useful for keeping exhaust temps down with extra power. If you fill in your sig. maybe we can be more helpful.
