6637, Good stuff?
Just wondering, I was thinking of replacing my stock box with the 6637 from Riff Raff,
Any problems or recomendations?
I know this is a common question, but I just wanted some new input from people who have been using it for a long time.
is it worth doing?

X2 on that
Cheaper filters, more filter material, better air flow... relatively cheap modification too. I don't think I've got a pic of mine posted yet.
Clay has it as a kit over at riffraff with a black powder coated adapter tube, t-bolt clamp and good looking Pete's cover. (Saves having to track down the parts separately, especially considering that his prices are so reasonable.) He's good people too.

Only downsides are increased noise (yes some of us DO want it quiet) and sucks air from under hood instead of out front.
It has been discussed and arguably proven that the underhood air vs fresh air doesn't really make any difference with the intercooler and turbo.

thats how I did mine. I bought it used with a K&N, you may have to trim the battery tray and you will have to remove the K&N box but the filter will slip right over the intake tube.
