Product Details

The Cometic C4477-140 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for BMW M30B34 and M30B35 inline-six engines. This precision gasket features a 93mm bore diameter and .140" (3.56mm) compressed thickness, providing superior sealing and durability for both stock and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for maximum durability and heat resistance
  • 93mm bore diameter designed for BMW M30B34 and M30B35 engines
  • .140" compressed thickness for optimal sealing
  • Superior resistance to blow-out and thermal cycling compared to composite gaskets
  • Embossed stainless steel layers with Viton rubber sealing beads
  • Reusable design allows for multiple installations when properly maintained

Cometic MLS gaskets are ideal for applications requiring exceptional sealing under high cylinder pressures, including turbocharged, supercharged, and high-compression naturally aspirated builds. The multi-layer construction accommodates minor surface imperfections while maintaining consistent clamping pressure across the entire sealing surface. Compatible with BMW 3.4L and 3.5L M30 engines found in various E24, E28, and E34 models.

Prices were good and the order shipped promptly. The email notice of shipment was a little late. It came after the order had arrived.

nothing yet.

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

Product delivered as expected within 4 days. Lowest price on the web. No complaints.

This was an easy transaction, keep me notified thoughout the entire shipment. Price is what got my attention in the first place. I will be back for future needs.

Nobody else had part in stock. Instant shipping and a good price. Will do business again!
