Product Details

The Cometic C4328-140 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for BMW M50 and M52 engine families. This precision-manufactured gasket features an 85mm bore diameter and .140-inch compressed thickness, designed to provide superior sealing performance in demanding applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for exceptional strength and durability
  • 85mm bore diameter optimized for BMW inline-six cylinder engines
  • .140-inch (3.56mm) compressed gasket thickness
  • Compatible with M50TUB24, M50B25, M50TUB25, M52TUB24, M52B25, M52TUB25, M52B28, and M52TUB28 engines
  • Engineered for both stock and performance applications
  • Superior combustion sealing and resistance to heat and pressure

Cometic MLS head gaskets utilize multiple layers of stainless steel with advanced coating technology to maintain seal integrity under extreme cylinder pressures and temperatures. The embossed design allows the gasket to conform to slight surface imperfections while maintaining consistent clamping pressure across the entire sealing surface. This gasket is ideal for enthusiasts rebuilding BMW engines or upgrading to higher performance levels.

Overall good experience.

Thanks for finding my part I inquired your company to list for my purchase, you guys are great!

Fast and easy, great price.

I just bought two of the new Aeromotive pumps from autoplicity at the best price found online.. They were shipped out quick and arrived even faster than I thought. Autoplicity.com will be in my favorites when it comes to ordering parts for my 94 Supra from now on!!!

Love it first time using you guys

My first experience with Autoplicity has been great. One of the best prices I found for the item. Too, the company is not secretative about itself such as another parts discounter.<br><br>Autoplicity is now "bookmarked" for future purchases!

Great price! Quick shipping. The intake I ordered was $20.00 cheaper than anywhere else I looked. Item was instock and shipped quick. Will order from Autoplicity again!

Great Seller. Fast Shipping and great prices!

Great price and great service highly recommended. Will purchase again

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.

Great prices, fast shipping. Would recommend.

Great prices, quick processing, and an overall excellent company
