He doesn't know what he's talking about.On the intake I went to my dealership and talked with the head mechanic, his info to me was to get an meteral not metallic so the air would not pickup the heat from the piping, the pipe in the finder is still there.. after the shop reopens I'll get it tested an post it here..
Air in the engine compartment is already too hot, that is the reason people install C.A.I.'s.
True C.A.I.'s draw air from outside the engine compartment. Your vehicle already had a C.A.I. system, but you got rid of it.
