Product Details

The Cometic C4348-070 is a multi-layer steel (MLS) cylinder head gasket engineered specifically for BMW M42B18 and M44B19 engines. This precision gasket features an 85mm bore diameter and .070-inch compressed thickness, providing reliable sealing for performance and stock applications.

Key Features:

  • Multi-layer steel construction for superior sealing and durability
  • 85mm bore diameter designed for M42B18 and M44B19 BMW engines
  • .070-inch (1.78mm) compressed gasket thickness
  • Accommodates thermal expansion and cylinder head movement
  • Eliminates the need for additional sealants
  • Engineered for street performance and racing applications

Cometic's MLS gaskets feature multiple layers of stainless steel with an embossed sealing bead around combustion chambers and fluid passages. This design distributes clamp load evenly while maintaining proper torque retention, making it ideal for turbocharged, supercharged, and high-compression engines. The gasket's ability to recover from thermal cycling helps prevent head gasket failure in demanding conditions.

Excellent business. This is my second purchase and there will be more! I ordered my parts over the holiday weekend and they mailed them the Tuesday after Labor Day. The absolute BEST pricing you will get. You will not find a lower price else ware. The shipping doesn't even take forever like most places you get great pricing. Communication is excellent, the site is very easy to use and navigate. I will be doing business with Autoplicity.com many more times and highly recommend them.

Great Price and fast ordering

Super Fast! Website was easy to user, multiple different payment options (Amazon, Paypal, Credit Card) Got a notification of shipment within 1 hour!

Website is easy to navigate. Parts are easy to find. Checkout was very simple to use. Good overall service.

Thanks

5 STAR MERCHANT! Recommend to everybody. Extremely quick, relieable, honest, and accurate. Item was delivered 2 days sooner than they told me in perfect condition. Additionally, they were the least expensive for the item. I do not know how they do it but they did it.
