Product Details

The Cometic C5860-040 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for the Subaru EZ30D Mark I engine. This high-performance gasket features a 90mm bore diameter and a compressed thickness of .040 inches, providing an optimal seal between the cylinder head and engine block.

Key Specifications:

  • Compressed thickness: .040 inch (1.02mm)
  • Bore diameter: 90mm (3.54 inches)
  • Multi-Layer Steel (MLS) construction for superior sealing
  • Right-hand side (RHS) application
  • Application: Subaru EZ30D Mark I horizontally-opposed 6-cylinder engine

Multi-Layer Steel Technology:

Cometic's MLS gaskets feature multiple layers of stainless steel with advanced coating technology that provides excellent rebound characteristics and superior seal under extreme temperatures and pressures. The embossed layers create a more effective seal around combustion chambers, coolant passages, and oil galleries compared to traditional composite gaskets.

Performance Benefits:

  • Enhanced durability for stock and modified applications
  • Excellent resistance to compression and thermal cycling
  • Superior torque retention and reduced gasket failure
  • Maintains seal integrity under high combustion pressures
  • Compatible with aluminum and cast iron cylinder heads

This gasket is ideal for engine rebuilds, performance applications, and turbocharged builds where reliable sealing under demanding conditions is critical. Cometic gaskets are manufactured in the USA using aerospace-grade materials and precision manufacturing processes.

Shipping was 5.00 on a 1.99 part but considering ebay was asking 18.00 for it I'm very happy

product just as described, received in 3 days

Fast, easy and very competitive prices. The customer service was very good with a quick and helpful response. I will shop here again!

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

Great prices will shop here again.

Excellent on-line merchant with outstanding customer service and the best prices on equipment and shipping. Highly reccomended!

Good prices and easy ordering process (order #18003). The only issue that I had was after placing the order, completing the entire process, I received three emails stating that "We noticed that you started checking out on our site, but didn't quite finish the process". After calling customer service, they ensured me that the order was complete. Since then, I receive the same email(3 emails at a time) on a daily basis. Just a little annoying, but easy enough to delete.
