But for those that care about heat and want to run the filters behind the bumper it doesn't seem that hard to do. Looking at the stillen gen 3, right before the MAF housing is about a 45* bend in the pipe. A simple 2.5" silicone coupling in a 45* bend would do nice. Same goes for the 90* bend around the core support. So 4 couplings, 2 filters, and a foot or two of 2.5" aluminium pipe off eBay and it seems pretty easy. I'm guessing around $100 or so. If you want to do the whole system pick up the post MAF tubes from Z1 or else where for $108-125 and you got what I'd say is a pretty simple, cheap, CAI.

Anyone do it because I didn't see it in the DIY section?
