Just looked at the S&B, they look really nice. But I still have to wonder what the big advantage of that is vs. just putting in a good filter..
The factory one has a snorkel that goes through the fender, so it's getting as cold of air as possible. The filter is like 1ft square.
The only real advantage i see is that the tube going from the filter box to the turbo is smoother. Is that going to be my only advantage, besides the fact that it looks much better?
They also offer a intake elbow. I've heard that those help quite a bit also. But once again i just look at it and don't see a big difference..
We all do the cold air intake because it's a fairly cheap upgrade, but it's still $300.00, and i wonder if I would really get $300.00 worth of performance out of it.
I would almost think the intake elbow for about the same money would give more performance.
Personally I would guess that exhaust, and turbo upgrade would be your best upgrades, and also maybe a tuner.
But i really don't know much of anything about diesels. So i'm just guessing at this point. Once I get it on the road i might start doing a little more research on it, and possibly some upgrades.
