Parts for your 2022 Mitsubishi Asx-Exhaust gasket

2022 Mitsubishi ASX exhaust gasket — what it is, why it matters, and when to replace

Technical references confirm the 2022 Mitsubishi ASX does use exhaust gaskets. The Mitsubishi Motors Workshop Manual for ASX/RVR/Outlander Sport (Group 15: Exhaust) specifies gasket replacement when disturbing the exhaust manifold and flange joints, and the Mitsubishi ASA/EPC parts catalogue lists multiple exhaust gaskets for the GA-series ASX (manifold-to-head and flange/crush ring gaskets). Major aftermarket catalogues in Australia and New Zealand (including Permaseal and other OE-equivalent suppliers) also range dedicated exhaust gaskets for 2010–2022 ASX models. So yes—exhaust gaskets are relevant and fitted on the 2022 ASX.

On the 2022 Mitsubishi ASX, the exhaust gasket’s job is simple but critical: it seals the joins where the exhaust manifold meets the cylinder head and where sections of the exhaust bolt together downstream. These gaskets—usually multi-layer steel at the manifold and a metal “donut” or flat ring at flange joints—keep hot gases inside the system so the car stays quiet, clean, and runs the way it should.

When a gasket starts to leak, the driver might notice a ticking or puffing noise on cold start, a bit of soot around a joint, or an exhaust smell. Because the ASX relies on oxygen sensors and the catalytic converter sitting close to the engine, any leak upstream can throw off sensor readings, nudge fuel trims out of whack, and even light the check engine lamp. Left too long, it can pit mating surfaces and make later repairs pricier.

During regular servicing, it’s smart to have the exhaust joints visually checked. If any section is removed—say, to access other components—new gaskets should go in as a matter of course. The ASX uses spring-loaded hardware in places to keep tension on crush gaskets
