Mr. Gasket 4808G - Header Gasket Gen V LT1/LT4 2014 to present, Oval Port

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 .072" Features: • Fits 2014 & up GM Gen V LT1/LT4 Engines • Multi Layer Stainless Steel • Oval Port 1.83" x 2.24" • Will not deteriorate from scrubbing action caused by different expansion rates in aluminum and steel materials. • Thickness .072" • 3-Layer Gasket Conforms to Header Flanges Better Than OEM 2-Layer Design
