I just picked the Wix up at Napa. It was arouned $50.00 if I remember right. Jethrro

 

50$!? I got mine for 32$ , and that is canadian money!

 

I just installed my BHAF and prefilter Friday, and I agree it is definitly something I should have done as soon as I got the truck, I had a new stock filter on it (about two weeks old) and after installing the BHAF it dropped my EGT's about 100* and I gained 2 psi of boost and the turbo does seem to spool faster!
