Product Details

The Cometic C5921-040 is a high-performance multi-layer steel (MLS) cylinder head gasket engineered specifically for GM LSJ Gen-1 Ecotec engines. This precision-manufactured gasket features an 87mm bore diameter and .040" compressed thickness, providing an optimal seal between the cylinder head and engine block.

Key Features:

  • Multi-layer steel construction for superior durability and heat resistance
  • 87mm bore diameter designed for LSJ Ecotec applications
  • .040" (1.02mm) compressed thickness for proper compression ratio
  • Advanced coating technology ensures excellent sealing under extreme conditions
  • Eliminates leak paths between cylinder head and block
  • Ideal for turbocharged and high-performance builds

Cometic MLS gaskets utilize multiple layers of stainless steel with specialized coatings to provide maximum sealing performance in demanding applications. The LSJ Ecotec engine, found in vehicles like the Chevrolet Cobalt SS and Saturn Ion Redline, benefits from this gasket's ability to handle increased cylinder pressures and temperatures common in forced induction setups.

Very fast shipping, received it Monday when I ordered it on Thursday. Thanks!

Easy to use, great prices and fast delivery too

best price online. fast shipping and wright part. I recommend this site to anyone!

Happy with the purchase! The lowest price and fast shipment.

I have used them a couple times. Always seem to be one of the lowest prices on the internet and pretty quick turnaround on shipping. If you live near Los Angeles, they have a warehouse in Cerritos, so things arrive real quick once they're shipped.

I ordered a water pump from them and that Amazon was advertising as a Chrome pump. When I discovered it was not chrome, I asked to cancel the order which was prior to shipping notification. I was told by customer service it had already been sent and I would have to wait until the item was sent for a return to be processed. The return was sent back and all money was credited to my account as promised.
