Does anyone know if any sealant is needed on the thin metal intake manifold gasket used on the 2.4 accords? Any help will be appreciated.

If it's a silicone beaded gasket, do not use sealer. Or if it's a crush-type metal gasket. Otherwise, probably yes.

Most gasket makers have good tech lines you can call and ask if you have doubts....

No, just the gasket.

Thank you for the info guys. I got no reply on this subject from the gasket company.
