Mitsubishi 4N15 2.4L Cylinder Heads & Engine Parts (2015–Present)

Looking for a premium aftermarket replacement Mitsubishi 4N15 2.4L MIVEC turbo diesel cylinder head? We supply brand-new complete heads, gasket sets, and internal engine components from premium Australian stock with rapid nationwide delivery.

The all-aluminium Mitsubishi 4N15 2.4L engine (MQ/MR Triton, Pajero Sport) is a highly efficient power plant, but thermal stress can warp or crack the head casting. Common symptoms of a failed 4N15 head include unexplained coolant drop, a hard cooling system hose, or consistent bubbling in the overflow tank.
