Product Details

The Cometic C4278-075 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Toyota 7M-GE and 7M-GTE inline-six engines. This high-performance gasket features an 84mm bore diameter and 0.075-inch compressed thickness, making it ideal for both stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme conditions
  • 84mm bore diameter designed for Toyota 7M-GE (naturally aspirated) and 7M-GTE (turbocharged) engines
  • 0.075-inch (1.9mm) compressed thickness allows for precise compression ratio tuning
  • Eliminates the need for additional sealants—install dry for optimal performance
  • Resists combustion chamber pressures and maintains seal integrity in high-boost applications
  • Embossed stainless steel layers with viton rubber coating for maximum conformability

Cometic MLS head gaskets are the preferred choice for engine builders and performance enthusiasts working with Toyota Supra, Cressida, and other vehicles equipped with 7M engines. The advanced MLS design accommodates thermal expansion and engine movement while maintaining consistent cylinder sealing, making this gasket suitable for street, strip, and forced induction builds.

Awesome

Order was received promptly

great

Fast delivery and good intake manifold.

Looks like dust shields will work great. Good price, free shipping and fast Service. Thanks John

Good price on the fuel pump, and reasonable shipping rate. Now we'll see how soon it arrives and if it's a real walbro not a knock off.

Website was fairly intuitive. Would be nice to have a search feature.

Good store to deal with.<br><br>Will purchase from them again.

I am happy with the prices and the free shipping.

I was very surprised that even with shipping, I saved 40% over the exact same item at a local auto store. They shipped the next business day and I am expecting to receive within 1 week of placing the order.<br>Autoplicity's website is easy to navigate and the selection and prices are top notch. I will be ordering from here again!

I ordered a Volant cold air intake for my truck,, really fast shipping and product got home without a scratch,,great website,,this is my first time shopping at autoplicity and im definatley going to shop there again.
