Overview

Mr. Gaskets Multi-Layered Steel Exhaust Manifold Gaskets offer modern gasket technology and sealing to your engine!

Features:

  • Multi-Layered Steel (MLS) exhaust and header collector gaskets are designed for extreme cylinder pressures produced by high horsepower high compression turbo-charged, supercharged and nitrous oxide injected engines.
  • Manufactured from three stainless steel layers, they resist corrosion, will not burn through or push out and maintain maximum fastener torque retention.
  • Stress formed inner and outer layer embossments act like springs that rebound under exhaust flange clamp load, creating force to seal extreme exhaust pressures. Total gasket thickness .075".
  • Will not deteriorate from scrubbing action caused by different expansion rates in aluminum and steel materials.
