Exactly - Water injection is NOT for cooling the intake air.
The phenolic spacer is made of a resin, it is similar to fiberglass but not quite the same. It is an EXCELLENT insulater even if only 3/8" thick, and does its job quite well.

Heat wrap will help cool off the ic pipes.

Heat wrap is not an active cooling solution. It is an insulater much like the spacer - it prevents heat transfer. But once the pipe beneath the wrap is heated it will take just that much longer to cool off because it is insulated from the ambient air. If you are seeking to reduce underhood temps your best bet is to start insulating items that emit heat, such as the numerous exhaust components.
