Parts for your 2011 Mitsubishi Outlander-Manifold gasket

2011 Mitsubishi Outlander manifold gasket — what it does and when to change it

Technical sources confirm the 2011 Mitsubishi Outlander uses manifold gaskets. The Mitsubishi Outlander 2011 Service Manual (Engine sections for 4B12 2.4L and 6B31 3.0L), the Mitsubishi ASA/CAPS genuine parts catalogue, and recognised aftermarket application guides (Fel‑Pro, Mahle, Victor Reinz) all list intake and exhaust manifold gaskets for these engines. That means the Outlander runs gaskets where the intake manifold meets the head and where the exhaust manifold bolts to the head and, on some variants, at the manifold-to-front pipe joint as well.

On this Outlander, the manifold gaskets do the quiet achiever’s job of sealing two very different sides of the engine. Intake gaskets keep unmetered air out so the ECU can hold fuel trims steady and keep the idle smooth. Exhaust gaskets keep hot gases in the exhaust stream so the O2 sensors read cleanly, the cabin stays fume‑free, and there’s no annoying tick on cold start. Whether it’s the 2.4‑litre four or the 3.0‑litre V6, good sealing protects performance, economy and emissions — and helps with WOF/RWC compliance in NZ and Australia.

There’s no fixed kilometre interval for replacement
