Product Details

The Cometic C4477-070 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for BMW M30B34 and M30B35 inline-six engines. This high-performance gasket features a 93mm bore diameter and .070-inch compressed thickness, providing exceptional sealing capabilities for both stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior strength and durability
  • 93mm bore diameter engineered for M30B34 and M30B35 engines
  • .070-inch (1.78mm) compressed thickness for precise engine sealing
  • Advanced coating technology prevents corrosion and enhances sealing performance
  • Designed to withstand extreme cylinder pressures and temperatures
  • Provides excellent rebound characteristics to maintain consistent clamping force
  • Ideal for both OEM replacement and performance builds

Cometic MLS gaskets utilize multiple layers of stainless steel with specialized coatings to create a gasket that can adapt to minor surface imperfections while maintaining a superior seal. This design makes them particularly well-suited for high-performance applications, forced induction setups, and engines that experience significant thermal cycling. The .070-inch thickness allows for precise compression ratio tuning when building or rebuilding your BMW M30 engine.

product just as described, received in 3 days

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.

easy ordering

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.
