Mitsubishi Pajero Sport Glow Plugs Malaysia — 4N15 Diesel
The 4N15 diesel uses glow plugs (not spark plugs). Glow plugs heat the combustion chamber for cold starts. In Malaysia's climate, glow plug issues are less critical than in cold countries but still matter for starting reliability. Check at 80,000 km — a failing glow plug causes hard starting in the morning, especially after overnight rain or when engine is cold from extended non-use. Bosch or NGK equivalent glow plugs. 4 plugs total.
