So I'm in the process of routing cooler air to the TB by doing the ram jet snorkel, removing rain/snow backing, and improving the air let areas.

I was checking engine compartment temps as I always do and noticed that the outside face of the Big Gulp nearest the header gets to 115F. The inside face nearest the filter reaches 100F and the edge of the filter reaches 85-90F, etc., whereas the headlight side of the filter was nearer to ambient. So, I covered the outside of BG with DEI heat shield.

The BG also did not fit the body panel or hood well, and there were gaps between the BG's pieces, so, I filled all those gaps with insulation. The BG surfaces now run much closer to ambient. I can already see improvement in IAT and MAT. The snorkel and headlight area work is next week.

The point is, I was surprised that mine needed this rework. Your CAI also might not be as efficient as it could be.
