I have a 93 base and just installed the M2 airbox. There is a small square opening now in the plastic material in front of the IC. I had to remove the large plastic piece that covered it up (plastic piece spans the width of the car) because of the airbox.

I was wondering what everyone did to cover that piece up to keep airflow thru the intercooler?

 

duct tape

 

fab it outta fiberglass or ABS plastic stock and a dremel tool..

 

duct tape fixes ANYTHING!

sorry... had to be said...

I'm going to be installing an M2 cold air box soon myself and was thinking about putting a pretty large, even bead of silicone around the edge, letting it cure for a little while, then mounting an aluminum plate over the top of it held down by sheet metal screws or something similar...

at least until I get a new intercooler and duct...

 

You know the old adage....

Can't duc' it, **** it!
