Premium Exhaust Manifold Gasket

This high-heat sealing gasket sits between the cylinder head and the exhaust manifold. Its job is to lock hot gases inside the runners, protect sensors, and keep turbo response sharp. A tight seal keeps noise down, prevents fumes, and stops power loss. Perfect for high-output Nissan performance setups where heat and pressure are extreme.

Why you need it ️

It prevents exhaust leaks that steal torque, slow turbo spool, and confuse O2 readings. It also shields nearby parts from heat, helping fuel economy, smooth idle, and long-term engine health.

How it works

Made from multi-layer stainless with heat-resistant coating, it compresses evenly under proper torque. Micro-sealing around ports and studs handles thermal expansion, keeping a stable seal through boost and heat cycles.

When it fails ⚠️

Common signs: ticking or whistle on cold start, soot at the flange, burning smell, slower spool, loss of power, higher fuel use, and possible CEL. Long-term leaks can warp the manifold, overheat wiring, and stress exhaust valves.

Tech & install notes ✅

• Clean, flat mating surfaces; check for warpage.
• Install dry; no extra sealant on MLS types.
• Use new hardware; torque center-out in stages.
• Recheck fasteners after a few heat cycles.
• Inspect heat shields and studs while in there.
