I was surprised how hot the stock intake tubing got after I took a short ride and was wondering if I should wrap the exhaust manifold to lower under hood temps. and possibly intake temp.?
Do you have the stock manifold, or a header? If you have the stock manifold, do you have the heat shield on it?
Wrapping your manifold and intake tube aren't going to hurt anything - I just don't think you'll see any marked improvement.
