Are you dealing with exhaust leaks or rattling under the hood? The right OEM Exhaust Manifold Gasket 17173‑21020 could be the solution.

It’s the factory-grade gasket sealing the exhaust manifold to the cylinder head on many Toyota and Scion 1.5 L models from 2000–2019, engineered to prevent leaks and ensure optimal engine performance.

Let’s explore five real Google PPA questions people ask about this part, so you can find precise answers and make informed decisions.

What vehicles does part 17173‑21020 fit?

Curious if your car is compatible with this gasket?

It fits Toyota Yaris, Prius, Prius C, Echo, and Scion xA/xB with 1.5 L NZ-series engines produced between 2000–2019.

Why is fitment accuracy important?

Using an incompatible gasket causes exhaust leaks, misalignment, and engine inefficiency. Always verify via VIN or vehicle picker on OEM parts sites.
