Plenum Spacer Q?

[darkfa8]

I bought a 1/2" phenolic plenum spacer for my car and was wondering if I need to get longer bolts/studs for the plenum?

It's a great time to get some longer black allen-head bolts.

Be really careful when you are re-installing your plenum to not over-tighten your (new) bolts.
