About this part

Product Details

If you're rebuilding the top end of your 1991-1998 Nissan 240SX or Silvia with the KA24DE engine, a solid head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of performance engines.

This gasket uses multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This combination ensures a strong seal between the cylinder head and the engine block, whether you have aluminum heads with an aluminum block or aluminum heads with a cast iron block. The compressed operating thickness is .040 inches, and the bore size is 91mm, making it a direct fit for the specified Nissan engines.
