What's the diameter of the flange on the MAF (where a cone filter would mount to)? Is it 3"?

Instead of waiting for my completely incompetent boss to supply me with a filter (which he promised... lying sack of ____ ), I think I'll just order one from NOPI and get the heat shield project under way. Strike while the iron is hot.

It's dark and cold out, thought I'd just ask instead of freezing my butt off while taking the airbox apart. Okay, okay. I'm lazy.

Oh, and I'll probably need a volunteer with an SC to see if the prototype heat shield will work with the SC too.
