Product Details

The Cometic C4148-120 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for BMC 1275 A-Series engines. This precision-manufactured gasket features a 74mm bore diameter and 0.120-inch compressed thickness, making it ideal for street performance and racing applications.

Key Features:

  • Multi-Layer Steel construction provides superior sealing and durability
  • 74mm bore diameter designed for BMC 1275 A-Series engines
  • 0.120-inch (3.05mm) compressed thickness allows for precise compression ratio tuning
  • Embossed stainless steel outer layers with viton rubber coating for enhanced sealing
  • Resists combustion chamber pressure and temperature extremes
  • No re-torque required after initial installation

Cometic MLS gaskets are constructed from multiple layers of stainless steel with a viton rubber coating, providing excellent torque retention and superior reusability compared to traditional composite gaskets. This gasket is commonly used in classic British performance builds, including Mini Cooper, Austin Healey Sprite, and MG Midget applications equipped with the legendary A-Series engine.

Great price, great service, A+

Fast shipping, great product. Nothing more needs to be said.

great price and customer service

Im really pleased with the order process and will be ordering from them again

They had the parts I needed at the best price. I needed some questions answered to make sure I was ordering the right parts for a 4 year old car and they were very helpful when I called.

Best price on the internet for my parts. Shipped out the next morning.

Autoplicity had the air filter I needed in stock when NO ONE else did. They responded quickly and got my order shipped. The only downside was that the shipping cost (regular shipping) was quite high compared to things I have ordered from other places. Still, total cost was comparable to what I would have paid if I purchased it locally.

Ordered a Trac-Bar from Autoplicity, and didn't have any problems. WILL be back!
