ISR Performance Multi Layer Exhaust Manifold Gasket - Nissan SR20DET

The factory paper-style exhaust manifold gasket on the SR is one of those parts that quietly fails over time. Heat cycles, vibration, and bolt-load loss eventually open up a tick, then a leak, then a real problem. Swapping in a proper multi-layer steel gasket fixes it for good.

What It Does

Multi-layer steel construction keeps a tight seal between the head and the exhaust manifold even at elevated combustion temperatures. The layered design holds bolt load better than paper or single-layer gaskets, which means the seal stays consistent through heat cycles and high-boost spikes. Sealing surface designed to handle the exhaust pressure produced by both turbocharged and naturally aspirated SR20 motors.

Fitment

All Nissan SR20DET and SR20DE motors. Works for stock replacement and aftermarket manifold installs.
