IM hacks anyone?

Spring is hear and I just spent the day cleaning out the car, and getting ready to change to summer tires. The car drives great these days, but I’m reminded of a few nagging issues I need to resolve.

The main one is that I’m still driving with the IM flaps removed. Plus, JHM still doesn’t have a date yet for their IM upgrade. Unfortunately, my flaps were in no position to be glued to either the long/short runner position, which is the recommended procedure.

But I’m wondering if it is possible to make/3-D print some sort of plate that will permanently cover the ports to the long runners (low-rpm driving)? Any experts out there with ideas on what material to use, etc? Something that would handle the temp/pressure changes in there.

That would make it easier to wait for the JHM upgrade…
