Message: [QUOTE="mjonesjr, post: 306383, member: 1076"] I got the AFE Big Boost filter today from JAP. I only paid $97 to my door including a recharge kit. After looking at the filter, I can say it is a quality filter. I really like how it has an air inlet in the end of the filter for more air area. The AFE Big Boost is about 1/2" shorter in length than the 6637. It clears the intercooler tubes a lot better than the 6637 filter did. Before I installed the filter, I drove the truck the same path and the same way. The most I could get the turbo to spool to was 19 PSI with the intercooler. After getting the filter installed, I took the truck for a spin. The turbo spools up a little faster and doesn't seem to be struggling to pull the air through. I can also tell a major difference in smoke output at 3/4 to WOT. There isn't near as much smoke as there was with the 6637 filter. I got the turbo up to 24 PSI obviously with the intercooler.
