Parts for your 2002 Toyota Ist-Manifold gasket

2002 Toyota ist manifold gasket — what it does and when to replace it

According to Toyota’s Electronic Parts Catalogue (EPC) and the factory Repair Manual for the NCP60-series ist (covering the 1NZ-FE/2NZ-FE engines), the 2002 Toyota ist uses both an intake manifold gasket and an exhaust manifold gasket. So yes, a manifold gasket is absolutely relevant and fitted on this model.

The manifold gaskets are the unsung heroes keeping the engine sealed where it matters most. Up top, the intake manifold gasket keeps unmetered air out so the engine doesn’t run lean, idle rough or throw codes like a P0171. Downstream, the exhaust manifold gasket seals hot gases as they leave the head, preventing that ticking leak at cold start, loss of low-end torque, fumes in the cabin and sooty stains around the manifold. On the ist’s small-capacity engines, good sealing helps maintain smooth drivability and proper fuel economy for everyday Kiwi and Aussie commutes.
