General comments:

Coat the header. Wrap is effective but has been known to catch on fire if it gets oil on it.

Create a heat shield for your intake - but in order to be legal in needs to be attached to your 'open' intake since there is no provision in the rules for just adding one as a stand alone.

Add some reflective heat tape to the intake tubing between your filter and throttle body now that that is 'open' as well.

I already have the intake tube insulated with reflective tape, easy fix.

If the "heat shield" only attaches to the throttle body then this would be the legal grey area? But, to be effective it would be best to duct some fresh air to the heat shield. Would this still be legal?

I think coating the headers is going on the Winter Project List.

The heat shield sounds interesting, anyone else care to comment?
