Hyundai i40 Fuel Injector Replacement Parts

The i40 was sold in the UK with both petrol and diesel engines, so fuel injectors exist across the range — though the type differs significantly between them. Petrol variants use port or direct fuel injectors, while diesel variants use high-pressure common-rail injectors, and the two types are completely different parts that do not interchange. When searching, always specify your fuel type (petrol or diesel) alongside your engine code to make sure you're quoted the correct injector.

The Hyundai i40 was produced as a single generation for the UK market, running from 2011 to 2019, with a facelift arriving around 2015. Within that generation, injector compatibility is driven primarily by the engine code rather than the model year, so a pre-facelift and post-facelift car sharing the same engine code may well use the same injectors — but ancillary and mounting changes can occur across the facelift boundary. Confirm fitment with the breaker against your exact registration before purchasing, as mid-production revisions can affect what bolts straight in.

For fuel injectors, trim level makes no difference whatsoever — SE, Style, Premium, and any other i40 trim grade all use the same injectors for a given engine. What determines compatibility is your engine code and fuel type, not the badge or specification level on the door sill. Pull your engine code from your V5 or a VIN check and supply it to the breaker, and the trim name can be set aside entirely.

The engine code is the single most important piece of information for sourcing a correct injector, sitting above year and trim in terms of what actually governs fitment. Common UK i40 engines include the 1.6 GDI and 2.0 GDI petrol units and the 1.7 CRDi diesel, each with its own injector specification. Your engine code appears on your V5 logbook or can be retrieved via a VIN check, and supplying it directly to the breaker is the most reliable way to get an accurate quote.

This is an important practical question and the honest answer is that it depends on the specific injector type and your vehicle's management system — some modern direct-injection systems require injector coding or adaptation via diagnostic equipment after fitting. Whether your particular i40 engine requires this, and whether a used injector can be successfully coded to your ECU, is something to confirm with the breaker or a qualified mechanic before committing to the purchase. Don't assume a used injector is a straightforward swap without checking this point first.

Body style has no bearing on fuel injector fitment — the injectors are part of the engine assembly, which is identical whether your i40 is a saloon or estate. The engine code, fuel type, and model year are what matter, and a breaker will use those details rather than the body style when identifying the correct part. Focus your search on supplying accurate engine information rather than worrying about which body style the donor car came from.
