Second Hand Nissan 350Z EGR Valve

No — the 350Z was never fitted with an EGR (Exhaust Gas Recirculation) valve in any of its variants sold in the UK. The 350Z uses a naturally aspirated 3.5-litre V6 petrol engine (VQ35DE or VQ35HR depending on the generation), and Nissan did not fit EGR systems to these engines in this application. If you have a fault code or are chasing an emissions-related issue, you may actually be looking for a different component such as the catalytic converter, oxygen (lambda) sensors, or the EVAP system — a breaker or independent specialist can help you identify the correct part against your registration.

It is almost certainly a mislisted or misidentified part, as the 350Z's VQ35 petrol engines were not equipped with EGR valves from the factory. Some online listings carry generic or incorrect part associations, so do not purchase an EGR valve on the assumption it belongs to this car. If you are trying to resolve an emissions warning or fault code, cross-reference the actual fault with a breaker or specialist who can look up the correct component against your specific registration number.

No — neither the pre-facelift 350Z (2003–2006) with the VQ35DE engine nor the post-2006 car with the revised VQ35HR engine was fitted with an EGR valve in the UK market. The change between those two generations brought improvements to the engine's variable valve timing and power output, but EGR was not introduced at either point. If you are comparing parts between early and late 350Z engines, the relevant differences to focus on are the engine code (DE vs HR), exhaust manifolds, and oxygen sensors rather than any EGR system.

Trim level — whether Touring, GT, or any other 350Z variant sold in the UK — makes no difference here, because none of them were fitted with an EGR valve; the absence of this part is consistent across all trims. For genuine emissions-related parts such as catalytic converters or lambda sensors, trim level still does not affect fitment — what matters is the engine code and model year. Always confirm specifics like catalytic converter compatibility with the breaker against your registration, as interchange across model years is not straightforward.

Depending on your fault code, the most likely candidates on the 350Z are the front or rear oxygen (lambda) sensors, the catalytic converters, or components in the EVAP (evaporative emissions) system such as the purge valve. The 350Z has a dual-exhaust system with separate catalyst assemblies for each bank of the V6, so it is worth identifying which bank the fault relates to before approaching a breaker. Catalytic converter compatibility can be sensitive to model year and engine code, so confirm the exact part needed with the breaker against your registration rather than assuming a direct swap.
