Here is my airbox. This is the front of it. Help me out!

Use paint and draw me where I should cut.

You also want to cut the front of the housing as well. All that gutting won't do any good unless you open that front portion up too :wink:

*dang* it sounds a lot better. Sounds like I got some power under there now! Will the FWI increase that effect of dampen it?

It seems to be running great now. Drilling holes doesnt seem neccesary right now. Especially since im gonna be getting a FWI. A lot more pickup. Somewhat faster. When i step on the pedal pretty good you hear it really start sucking air. sounds great
