Unless you plan on putting some serious horse power on the road a BHAF is more than suffecient. With what i have on my truck I dont believe a cold air in take is going to make enough differance to be worth the money. the BAHF will flow enough air for 3000 to 400 HP maybe more. someone here will correct me if i am wrong on the stated HP. I dont think that would be high on my list of mods. To many other good things out there that wil really make a differance in performance.

The problem with the compromises to plumb the CAI... can mean a smaller filter. The air flow is more important than the temperature.

the things i have found with a BHAF compared to a k&n or stock filter are theseturbo spools just a tad fasterthe massive surface area of the bhaf means that less air velocity per square inch=less crap to stick to the filter elementnice whistle tooi can shake my bhaf and nothing sticks to it cause the air velocity into the filter isnt enough to pull stuff in like the stocker.

I also am running the napa 6637. I made a bracket and hooked it to an exhisting bolt on the inside of the fender. Instead of a hole I made a slot (where it bolts to the fender) so all I have to do is loosen the bolt and the bracket slides off the bolt (upward) and stays attached to the filter. It takes two minutes to remove the filter now.

The smaller one has a smaller surface area but I'm sure it will work just as good. Throw a Outwears pre filter on it, help make it last longer and repel some water that might splash on it

Mine just lays in there, but i do like the braket idea. simple but very functional.

I have mine just laying there too. I don't even have a outerware on it either. :banghead: I will have to get one soon. Not driving it much right now. Sent from my Droid using Tapatalk

I have got the outer ware. They are pretty pricey. I think I spent near $30 for it. Had aliitle more cash then though.
