Aftermarket: Quality alternative. This is a quality alternative, designed to fit and function like the original part, often at a more competitive price.

Glow Plug Conversion Kit for the 2.25L diesel engine, replacing the original series-wired heater plugs with parallel-wired glow plugs. In the original arrangement the plugs are wired in series, so a single failed plug disables the entire pre-heat circuit; wiring them in parallel lets each plug operate independently, and the probe-type elements present a larger heated area to aid cold starting.

The kit contains four glow plugs, four leads and fitting instructions for rewiring the circuit. Individual glow plugs are available separately.

Frequently asked questions

What is the glow plug conversion kit for the 2.25L diesel?

The glow plug conversion kit replaces the original series-wired heater plugs on the 2.25 litre diesel with parallel-wired glow plugs. Wiring them in parallel lets each plug operate independently, and the probe-type elements present a larger heated area to aid cold starting. It fits the Land Rover Series 2 and 3 and early Defender 2.25 diesel.

What's included in the kit?

The kit contains four glow plugs, four leads and fitting instructions for rewiring the pre-heat circuit. Individual glow plugs are available separately if you only need to replace one later.

Why convert from the original series-wired system?

With the original series wiring, a single failed plug disables the entire pre-heat circuit, so the engine struggles to start cold. Converting to parallel-wired glow plugs lets each plug work independently, so one failure no longer takes out the whole system and cold starting improves.

Which vehicles does the kit fit?

It fits the Land Rover Series 2 and 3 with the 2.25 litre diesel, and early Defender 90 and 110 models with that engine (fitment notes give up to 1985). Confirm your engine is the 2.25 diesel before ordering, as later diesels use a different setup.
