Product Details

The Cometic C4495-040 is a multi-layer steel (MLS) cylinder head gasket engineered specifically for Nissan RB20DE and RB20DET engines. This precision gasket features an 80mm bore diameter and .040" (1.0mm) compressed thickness, making it ideal for both stock rebuilds and performance applications.

Key Features:

  • Multi-layer steel construction provides superior sealing and durability
  • 80mm bore diameter designed for RB20 engine specifications
  • .040" compressed thickness for precise compression ratio control
  • Exceeds OEM specifications for reliable sealing under high heat and pressure
  • Compatible with Nissan RB20DE and RB20DET inline-6 engines
  • Engineered to withstand high boost and elevated cylinder pressures

Cometic's MLS gaskets feature multiple layers of stainless steel with elastomeric coatings that respond to flange pressure changes, maintaining a consistent seal throughout the engine's thermal cycles. This design makes the C4495-040 an excellent choice for turbocharged RB20DET applications where reliability is critical.

Ordered an Fabtech steering box skidplate, best price I could find on the net was Autoplicity. Price was better than all the 4x4 sites I checked. Item is shipping directly from Mfg, so really can't comment on shipping speed. Otherwise, transaction was easy and I really like the fact they accept PayPal.

excellent service, i had to wait a few days for the order to be processesed, but only because i ordered on Friday afternoon, but love the site!

excellent ship time and exceptional pricing deffinatly will buy from here again

You guys are the only ones who had my part in stock. The shipping was quick and I was very happy with the condition of the bell housing that I ordered i would order from them again.

Smooth transaction, very pleased

They made a mistake with the shipping address, but, they took care of it very politely and professionally. Very nice. Thanks.
