Product Overview
Hard cold starting, white smoke immediately after startup or one cylinder that takes longer to fire can point to weak glow plugs after battery voltage and the glow circuit have been checked. Diesel engines rely on these heaters most heavily when ambient temperature is low.
These replacement glow plugs restore the preheating needed to help the engine light off cleanly during cold starts. Replacing a matched set can make sense when several plugs have similar service hours or resistance testing shows more than one weak unit.
