Product Details

The Cometic C4577-051 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for 1990-1994 Nissan SR20DET turbocharged engines in AWD applications. This gasket features an 88mm bore diameter and .051" (1.3mm) compressed thickness, making it ideal for stock to moderately modified engines.

Key Features:

  • Multi-Layer Steel construction provides superior sealing and durability under high cylinder pressures
  • 88mm bore diameter optimized for SR20DET engine specifications
  • .051" compressed gasket thickness maintains proper compression ratio
  • Designed specifically for AWD SR20DET applications (1990-1994)
  • Embossed stainless steel layers with elastomeric coating ensure consistent clamping pressure
  • Resists blowout and accommodates minor surface imperfections

Cometic MLS gaskets are a preferred choice for performance and racing applications due to their ability to withstand extreme temperatures and pressures while maintaining a reliable seal. This gasket requires proper surface preparation with RA finish between 50-60 for optimal performance.

- Updated review -<br>Autoplicity.com contacted me after my original review and admitted to making a mistake with my order. They have refunded my shipping and I am happy now.<br><br>- Original review -<br>After 18 days the part finally arrived. The filter appears to have been sent directly from K&N, but I ordered on the 20th of June, yet the packing date that K&N Engineering Inc. shows is July 3rd.
