Cheap Vauxhall Astra Fuel Injector

Both years fall within the Astra J generation (2009–2015), so there is a reasonable chance of compatibility if the engine codes match — the engine code is the single most important detail here, as injectors are engineered to the engine specification rather than the model year. However, there can be running production changes within a generation, so confirm the engine code from your V5 or a VIN check and route it to the breaker to verify the part number before buying.

The Astra H ran from 2004 to 2010 and the Astra J from 2009 to 2015 — these are distinct generations with different engine families, so injectors are very unlikely to interchange across that boundary. Match the engine code from your V5 to whatever the breaker has, and confirm directly with them before purchasing.

Trim level makes no difference to fuel injector fitment on the Astra — SE, Design, SRi, Elite and other trim names are cosmetic and equipment-based distinctions that do not change the engine specification. What matters is the engine code, fuel type (petrol or diesel), and the engine generation; give the breaker your engine code and they can match the correct injector regardless of which trim your car is.

Yes — fuel injectors are fitted to all Vauxhall Astra engines, both petrol and diesel; petrol Astras use port or direct fuel injection depending on the engine, while diesel Astras use diesel common-rail injectors, and these two types are completely different parts that will not interchange. Always confirm your fuel type and engine code with the breaker, as diesel and petrol injectors look similar but operate on entirely different systems and pressures.

A 2007 Astra sits in the Astra H generation (2004–2010), which was offered with a wide range of petrol and diesel engines, each with its own injector specification — searching by year alone will not narrow it down reliably. Pull the engine code from your V5 logbook or run a HPI-style VIN check, then give that code to the breaker so they can match the correct injector for your exact engine.

The Astra J ran from 2009 to 2015 and the Astra K from 2015 onwards — these are separate generations with different engine architectures, so injectors from an Astra K are not a straightforward match for an Astra J even if the displacement looks similar on paper. Share your engine code with the breaker and ask them to cross-reference part numbers; do not assume compatibility across that generation boundary.
