I was reading the past forum topics for intake ideas and I came across the one about drilling holes in the bottom of the factory air box for better performance. Someone actually asked this question, but got no response. So I guess I'll ask it again in hopes that someone will be able to help:

How big should you drill those holes? How far apart? Or does it matter the size at all?

I'm helpless, I need a walk through

Thanks, it's an ingenious idea

go to vw mods--- highly recomend this mod . $200 cai's only show slight gains over this mod. just make sure not to drill on the side that faces your engine.
