(TUR) MITSUBISHI 4M41T I4 DOHC – INLET FITS MITSUBISHI PAJERO GLX, GLS, EXCEED 1999-2006 4 DOOR 3.2 LITRE I4 16V PG428

Description

The (TUR) MITSUBISHI 4M41T I4 DOHC, produced between 1999 and 2006 in GLX, GLS, and Exceed trims. At first, it was a flagship SUV that combined rugged off-road capability with modern comfort and refinement. Central to its success was the 4M41T engine, a 3.2-litre inline-four turbocharged diesel unit with a DOHC (Double Overhead Camshaft) configuration and 16 valves. This engine powered the 4-door Pajero models, delivering strong torque, reliability, and efficiency. A critical component of its operation was the inlet system, referenced under part code PG428. This ensured efficient airflow into the combustion chambers as well as supported the turbocharged performance.

Engine Characteristics
