• Description:

  Left Side. Installation.

  This Genuine Mopar Left Side Exhaust Manifold Gasket (5038099AA) is the high-temperature structural seal designed to maintain the absolute backpressure integrity of your engine’s exhaust system. While "economy" composite gaskets often shrink, char, and "blow out" under heavy towing or high-RPM heat, this authentic OEM gasket is engineered to thrive in the punishing thermal environment of the cylinder head.

  The Advantage That Sets You Apart

  • Multi-Layer Steel (MLS) Technology: Engineered with a specialized multi-layer spring-steel construction. Unlike single-layer or fiber gaskets, this MLS design acts as a high-tension spring that maintains a constant "crush-seal" even as the manifold expands and contracts during extreme heat cycles.
  • Precision Thermal Recovery: Designed to handle "manifold warp"—a common issue where the exhaust manifold moves slightly relative to the head. This Mopar gasket features embossed sealing beads that "track" this movement, preventing the persistent ticking noises and "black soot" leaks common with rigid aftermarket alternatives.
  • High-Temp Viton Coating: The steel layers are treated with a proprietary, heat-resistant coating that fills microscopic imperfections in both the cylinder head and manifold surfaces. This ensures a 100% gas-tight seal from the moment of installation, eliminating the need for messy "gasket-maker" sealants.
  • Exhaust Velocity Optimization: Molded to the exact port geometry of your engine’s intake and exhaust path. By providing a perfectly flush transition, it prevents the internal turbulence that can disrupt exhaust scavenging and trigger "Oxygen Sensor" or "Catalytic Efficiency" fault codes.
  • Mopar Certified Protection: Backed by a Mopar 2-Year/Unlimited Mile Warranty, offering a level of professional mechanical accountability and nationwide dealership support that online-only "white-label" gaskets simply cannot match.
