Nissan Navara Glow Plugs Replacement Parts

Glow plugs only exist on diesel-engined Navaras — they are a diesel cold-start aid and are simply not fitted to any petrol variant. All UK-market Navaras sold new were diesel, so in practice virtually every Navara you'll find here will have glow plugs, but it's worth confirming the fuel type if you're unsure about an import or grey-market vehicle. If your Navara is diesel, you do need glow plugs; if somehow petrol, you'd be looking for spark plugs instead.

The D40 and D23 are different generations with different engine families, so glow plugs are not a straightforward swap between them — the D40 used 2.5 dCi engines (YD25DDTi) while the D23 moved to 2.3 dCi units (YS23DDT), and these engines take different plugs. Always match by engine code rather than by generation name or year alone. Supply your registration and engine code to the breaker so they can confirm the correct plug specification before you buy.

The D40 ran from 2005 to 2015 and the core 2.5 dCi YD25DDTi engine was used throughout much of that range, so glow plugs from one D40 year will often suit another of the same engine code. However, there were running production changes across the D40's lifespan, so confirm the engine code on your V5 or via a VIN check and quote it to the breaker rather than relying on year alone. This is the single most reliable way to ensure you get the right plugs.

Trim level makes no difference to glow plug fitment on the Navara — Tekna, Acenta, Visia, and any other trim all use the same plugs if they share the same engine code. Glow plugs are a purely mechanical engine component and are unaffected by interior specification, technology pack, or badge level. Focus entirely on matching the engine code when sourcing from a breaker.

A four-cylinder diesel engine like those found in the Navara has one glow plug per cylinder, so you need four in total. When buying from a breaker, you can often source a full set of four removed as a job lot, which is the most practical option. Confirm with the breaker that all four are from the same engine and specification to ensure consistency.

The D40 received a facelift in 2010, but the key question for glow plug fitment is always the engine code, not the facelift date. If the engine code remained the same across the facelift on your particular vehicle, the plugs are very likely compatible, but ancillary changes can occur mid-production without a formal facelift. Quote your engine code and registration to the breaker and ask them to confirm fitment against your specific vehicle rather than assuming the facelift boundary is the deciding factor.
