Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under high compression and extreme temperatures
  • .040" compressed gasket thickness allows for precise compression ratio tuning
  • 4.250" bore size designed for Chevrolet ZL1 Mark-IV Big Block V8 applications
  • Embossed stainless steel layers with Viton rubber sealing beads ensure consistent clamping pressure
  • Eliminates the need for additional sealants when installed properly on properly prepared surfaces

Great communication, Great prices! They beat all the competitors hands down on price for my cold air intake order #18986. Quick shipping and they are now in my favorites for places to look for automobile needs. The only thing I would like to see them change is the speed of their website.
