Peugeot RCZ Fuel Injector Replacement Parts

Fuel injectors exist on all Peugeot RCZ engines, but the type differs critically by fuel system: petrol engines (including the 1.6 THP turbo units) use port or direct fuel injectors, while the 2.0 HDi diesel engine uses high-pressure diesel injectors, and these are completely different parts that are not interchangeable. Always confirm whether your RCZ is petrol or diesel before sourcing, as getting the wrong type will not work at all. The engine code from your V5 or a VIN check is the single most reliable way to ensure a breaker supplies the correct injector for your exact engine.

The Peugeot RCZ was produced from 2010 to 2015 as a single generation with a facelift in 2012, so a 2010 and a 2013 car could potentially share injectors if they share the same engine code — but you must match the engine code exactly, as injector specification can vary even within the same displacement. The 1.6 THP engine in particular saw updates across the production run that may affect injector compatibility across the 2012 facelift boundary. Confirm the engine code on both donor and recipient vehicles with the breaker against your registration before purchasing.

Trim level on its own does not determine injector fitment — what matters is the engine code, and the RCZ R used a higher-output version of the 1.6 THP engine with a different state of tune, which means its injectors may differ from those in a standard 1.6 THP RCZ even though the displacement looks the same on paper. You should not assume an injector from a standard RCZ will suit an RCZ R without confirming engine codes match exactly. Give the breaker your full registration and engine code so they can verify the correct specification for your variant.

Yes, the 2.0 HDi diesel RCZ uses high-pressure common-rail diesel injectors, which are a completely different design and specification to the petrol injectors used in the 1.6 THP variants. Diesel injectors for this engine are precision-calibrated components and the engine code from your V5 is essential to ensure the correct part is sourced from the breaker. Be aware that diesel injector coding and ECU pairing requirements are something you should confirm directly with your fitting garage and the breaker, as this can affect installation.

Because the RCZ shares the PSA 1.6 THP engine family with models like the 308 and Citroen DS3, there is a reasonable chance of parts compatibility if the engine codes match exactly, and breakers will often source injectors across these platforms. However, you must confirm the engine code is identical — not just the displacement — as different states of tune and model-year revisions can mean different injector specifications even within the same engine family. Always route this comparison through the breaker against both registrations to verify before buying.

The RCZ 1.6 THP petrol engine has four cylinders and therefore four fuel injectors, one per cylinder, and the 2.0 HDi diesel likewise has four. Whether you replace one or all four is a mechanical decision best made with your garage — if one injector has failed, others may be worn similarly, but single replacements are common from breakers. Make sure any used injector sourced from a breaker matches your engine code, and discuss with your mechanic whether coding or balancing will be needed after fitting.
