ACDelco
Fel-Pro
For lower intake manifold gasket kits. Buick 3800 V6. The ACDelco has one seal that the Fel-Pro doesn't have, but the Fel-Pro has several seals that the ACDelco doesn't have. The ACDelco has a cleaner looking application of the sealant bead on the main gaskets. The Fel-Pro looks a little sloppy with its sealant bead application. I'm assuming they have robots apply the sealant at the factory.
