Nissan Interstar Exhaust Manifold Replacement Parts

Yes, every variant of the Nissan Interstar was powered by a diesel engine, and all diesel engines have an exhaust manifold — it is the cast-iron or steel collector that gathers exhaust gases from the cylinder head and routes them toward the turbocharger and the rest of the exhaust system. Because the Interstar was only ever offered with diesel power (no petrol option was sold in the UK), every example on the road will have one. What varies between vehicles is the exact specification, which is tied to the engine code and emissions era rather than trim level.

The Nissan Interstar (sold in the UK from around 2002 to 2010) was built on the Renault Master platform and used Renault-sourced diesel engines, most commonly the 2.5 dCi (G9U engine family) and the 2.2 dCi (G9T) in earlier examples. The exhaust manifold is engineered to the specific engine code, so you must match the code stamped on your engine rather than simply going by engine displacement or year alone. Give the breaker your registration and engine code together to make sure you get the right casting.

The Interstar ran through one main generation in the UK, but there were updates across its life — particularly around emissions compliance — that can affect ancillary exhaust components even if the core manifold casting looks similar. An early 2.5 dCi G9U manifold and a later G9U manifold may share the same basic design, but differences in EGR ports or mounting faces introduced during mid-life updates can cause sealing or fitment problems. Name the year boundary and your engine code to the breaker and ask them to confirm the part number matches before you commit.

No, trim level has no bearing on exhaust manifold fitment for the Interstar — the manifold follows the engine code and emissions specification, not whether the van is a base S or a higher SE grade. You may find cosmetic or interior differences between trim levels, but underneath the bonnet the engine and its exhaust manifold are determined by the powertrain option chosen at the time of manufacture. Focus on matching engine code, displacement, and emissions era rather than worrying about trim badges.

The DPF (diesel particulate filter) sits downstream of the manifold in the exhaust system, so the manifold itself is not a DPF-specific part; however, later Euro 4 and Euro 5-era Interstars may have had revised manifold designs to manage exhaust gas temperatures and EGR integration that suit the DPF system. Swapping a manifold from a pre-DPF vehicle onto a DPF-equipped one, or vice versa, could cause issues with gas flow, EGR connections, or sensor ports. Confirm with the breaker against your registration that the donor vehicle shared the same emissions specification as yours before purchasing.

The Nissan Interstar, Renault Master, and Vauxhall Movano of the same generation are closely related vehicles sharing the same platform and Renault-sourced engines, so manifold crossover is plausible where engine codes match exactly. However, small differences in ancillary bracketry, sensor ports, or EGR connections between manufacturer variants mean this is strong confirm-with-the-breaker territory rather than a guaranteed swap. Give the breaker both registrations and ask them to cross-reference part numbers before you buy.
