Cheap Ford Focus Glow Plugs

Glow plugs only exist on diesel-engined Ford Focuses — they are a diesel-specific part that pre-heats the combustion chamber to aid cold starting. Petrol-engined Focuses (including the 1.0 EcoBoost, 1.4, 1.6, 1.8, 2.0 petrol, and the ST and RS performance variants) use spark plugs instead and never had glow plugs fitted. If you have a diesel Focus — such as the 1.5 TDCi, 1.6 TDCi, 1.8 TDCi or 2.0 TDCi — then glow plugs are the correct part to be sourcing.

The Focus Mk2 ran from 2004 to 2011, while the Mk3 launched in 2011, so a 2010 car is Mk2 and a 2012 car is Mk3 — these are different generations with different engine families, so the parts are very unlikely to be interchangeable. Fitment of glow plugs follows the engine code above all else, so even within a generation you need to match the exact engine code (found on your V5 or via a VIN check) rather than relying on year alone. Supply your engine code to the breaker so they can confirm compatibility before buying.

No — trim level has no bearing on glow plug fitment whatsoever. Zetec, Titanium, Ghia, Studio, and any other trim badge simply reflect interior and equipment specification, not the engine, so two diesel Focuses with the same engine code will use identical glow plugs regardless of trim. The only details that matter are the engine code and fuel type, so focus on those when speaking to a breaker.

The Mk3 Focus ran from 2011 with a facelift in 2014, so both a 2014 and a 2015 car sit within the same Mk3 generation — however, Ford introduced the 1.5 TDCi engine as part of that 2014 facelift cycle, replacing the older 1.6 TDCi. If the donor 2014 car also has the 1.5 TDCi and you can confirm matching engine codes, fitment is likely, but confirm this with the breaker against both registrations to be certain.

No — whether your Focus is a hatchback, estate (Turnier), or saloon makes no difference to glow plug fitment. Glow plugs are determined entirely by the engine, so a 1.6 TDCi estate and a 1.6 TDCi hatchback with the same engine code will use exactly the same plugs. Just supply your engine code to the breaker and they will be able to match the correct part.

As a general rule, a diesel engine has one glow plug per cylinder — so a four-cylinder Focus diesel (which covers the vast majority of diesel Focus variants, including the 1.5 TDCi, 1.6 TDCi, 1.8 TDCi, and 2.0 TDCi) will have four glow plugs. The specific plug type and specification can vary between engine families though, so always match by engine code rather than cylinder count alone, and let the breaker confirm the exact part against your registration.
