header wrap?

[SLP IROC-Z]

is it really worth using? and if i were to wrap my headers, should i do the Y pipe to. how much cooler will my engine bay be and will the interior be a little cooler as well?

joe i noticed a big improvment in my engine bay. My engine is still crazy hot, but the under hood temps went way down. Plus they also sell black wrap so it'll look nice and clean on those headers. If you take your time and wrap them tight i'll come out nice.
