ISR Performance OE Replacement RWD SR20DET S13/14/15 Exhaust Manifold Gasket

This ISR Performance OE replacement exhaust manifold gasket seals the exhaust manifold to the cylinder head on the Nissan RWD SR20DET and fits S13, S14 and S15 engines alike. Whether you are reinstalling the factory cast manifold or bolting on a tubular aftermarket one, the gasket between the manifold and head is the same, and it needs to be new.

The leak you can hear

An exhaust manifold gasket that has blown out announces itself with a sharp ticking on cold start that fades as the metal expands. Beyond the noise, the leak lets exhaust escape ahead of the turbo and reduces the energy driving the turbine, so spool suffers. On a car with a wideband sensor, it can also skew readings by drawing air into the stream.
