COMETIC Primary Gasket Kit C9150

A primary gasket kit is only as good as its ability to seal consistently under extreme heat and pressure—and that's where Cometic's AFM material excels. If you're running a high-performance engine, factory gaskets won't cut it; they'll blow out, leak, and cost you reliability when you need it most. The C9150 kit gives you OEM-quality sealing across your entire primary assembly with materials engineered to handle sustained temperatures exceeding 2500°F.

What sets this kit apart is Cometic's proprietary Aluminum Foamette Material construction. The aluminum core bonds with a chemically blown nitrile synthetic rubber outer layer, creating a gasket that recovers 85% of its shape while maintaining superior torque retention. This means fewer compression losses, better sealing longevity, and the confidence that your primary won't weep oil or coolant during hard runs. Installation is straightforward—no gasket sealer required—and the kit includes every gasket, seal, and O-ring you need for both inner and outer primary assembly.
