Product Details

The Cometic C4478-070 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for BMW S38B35 and S38B36 inline-six engines. This aftermarket head gasket provides superior sealing performance for high-performance and racing applications where stock gaskets may fail under increased cylinder pressures.

Key Features:

  • Multi-Layer Steel construction with multiple layers of stainless steel for maximum strength and durability
  • Advanced coating technology ensures proper seal between head and block surfaces
  • Engineered to withstand extreme temperatures and pressures in forced induction and high-compression applications
  • Direct replacement for BMW S38B35 (3.5L) and S38B36 (3.6L) engines found in E28 M5 and E34 M5 models
  • Precision-cut bore and bolt hole patterns ensure exact fitment
  • Reduces gasket failure common in high-performance builds

Cometic gaskets are the preferred choice of professional engine builders and performance enthusiasts who demand reliable sealing under the most demanding conditions. This head gasket is ideal for engine rebuilds, performance upgrades, or turbo/supercharger installations where cylinder pressure exceeds factory specifications.

I purchased an extend-a-truck on autoplicity. It was the best price on the Internet. Autoplicity beat amazon by approximately $30. I received a confirmation it shipped the following day.

Great pricing and customer service. Item shipped on time and with no complicaitons. Best pricing on the internet that I could find. Great seller.

I ordered my K&N cold air intake order number 17133<br>From autoplicity for almost half price compared to other sites online. I will continue my purchases here n stop my searches elsewhere. And delivery time is fast!

Great service, best price available online and realistic shipping costs, Ordered 5PM Friday, shipped Monday , received Tuesday end of day. Beats driving to the local store. Highly recommended !!<br><br>RS Larchmont NY
