Ensure reliable cold starting performance with this Genuine Nissan Glow Plug Relay, designed specifically for Nissan Patrol GQ and GU models fitted with the TD42 diesel engine. This OEM relay is a critical component of the glow plug system, controlling the high electrical current required to heat the glow plugs before engine start-up.

The glow plug relay plays an important role in pre-heating the combustion chambers, allowing your diesel engine to start efficiently, particularly in colder conditions. Over time, internal relay contacts can wear, burn, or fail due to repeated electrical loads, heat cycles, and engine bay conditions. A faulty relay can prevent power from reaching the glow plugs, resulting in difficult starting, excessive cranking, and poor cold-start performance.

Manufactured to Nissan's original specifications, this genuine direct-fit replacement provides accurate glow plug control, reliable electrical operation, and long-lasting durability without the need for modification.
