Parts for your 2007 Toyota Ist-Manifold gasket

2007 Toyota ist manifold gasket — what it is, why it matters, and when to replace it

Yes, a manifold gasket is absolutely used on the 2007 Toyota ist. Toyota’s Service Information (TIS) repair manuals for the NCP60/NCP61 (1NZ‑FE) and ZSP110 (2ZR‑FE) platforms, along with Toyota’s Electronic Parts Catalog (EPC) diagrams, show both intake manifold gaskets and exhaust manifold gaskets fitted to this model year and its engines. Those factory sources specify gasket part positions, sealing faces, and removal/installation procedures, confirming the component’s relevance on the 2007 ist.

On this car, the intake manifold gasket seals the junction between the intake manifold and the cylinder head, keeping unmetered air out so the engine can manage fuel trims properly. The exhaust manifold gasket seals hot exhaust gases at the manifold-to-head interface to prevent leaks, protect nearby components, and keep emissions equipment working as designed. When either gasket fails, it can cause rough idle, a ticking or hissing noise, increased fuel use, engine light with lean codes, or a sooty smell from the bay.

There’s no fixed replacement interval for manifold gaskets on the 2007 ist
