BHAF

[Texas CTD]

I went to NAPA Truck Parts, here in town, and asked about the 6670. THey have to order it, and they want... ... $68!! Eff that!

My NAPA wanted $68, and I said eff that too!

Only gain you'll see is the filter last a lot longer and passes only clean air. EGT's and HP/TQ gain are going next to nil.

Well if I get that AND get to hear the turbo more then that's good enough for me!

Thanks! A bungee cord would hold it better, and would make things quicker if I had to remove the BHAF. They're the same filter. Both are 10.5" x 10.5". For $46 (before shipping) you can get a NAPA 2790. It's outer diameter is 10.5", but it's almost 12" tall. http://www.fleetfilter.com/filter/wix-air-filters/42790.html Some say it's better, some say it lasts longer, but I'd rather save 12-13 dollars and use the 6637 - nothin' wrong with it, and it will last a long time. . . I don't see another 1.3 inches of filter giving you a whole lot more life out of the filter. . .

The 6637 I bought is only 8.5" in diameter where as the bhaf from Vulcan is 10.5" in diameter. It also seemed to have a stiffer outlet to clamp to.

Hmm, well I'm gonna have to measure mine and see - I coulda swore they were all 10.5"x10.5".

I went back to the picture you posted and appear to have the same one I now have. That is why there is so much room there. My old bhaf really filled the space up. NAPA sold me the 6637 for $33.

Installed it.. The turbo to filter hose is really snug-fitting, but perfect, IMO. The flange on the filter is quite firm and seals to the hose really well.

for the time being, I split a pice of 1/2" hose and covered the AC line. I'll make a mount this weekend for it.

When I installed mine there is no contact between the filter and AC lines. I wasn't sure I was going to do anything to it, but I suppose it is cheap insurance...

I used 1/2 inch foam pipe insulation on my A/C pipe to protect it. Also under that is a piece of rubber hose just in case.
