I did a search, but didnt see anything, so here goes.
I want to do a few things.
The air filter is an open element K&N and I want to build a box or sheild to keep heat from the headers. I then want to put a shield to stop air from entering the engine compartment through a large opening I have next to the radiator. I could even direct some air from this opening toward the air filter?
Wondering about the legality of this...
