Cheap Nissan Primera Catalytic Converter

Yes, all petrol-engined Nissan Primeras were fitted with a catalytic converter as standard, as they are required for emissions control on petrol engines. The Primera was sold in the UK across three generations — the P10 (1990–1996), P11 (1996–2002), and P12 (2002–2008) — and petrol variants across all three generations carry a cat. The diesel variants used in some P11 and P12 models use a different emissions system, so if you have a diesel Primera you should confirm with the breaker exactly what emissions hardware is fitted to your specific engine.

The P11 and P12 are different generations with different engine families, different exhaust configurations, and different emissions standards, so a direct swap across that generation boundary is very unlikely to work. Even if the flanges looked similar, you could end up with a cat that does not match your engine's emissions calibration, which risks an MOT failure. Confirm the exact engine code on your V5C and ask the breaker to match it specifically to a P12-sourced unit rather than assuming cross-generation compatibility.

Trim level — whether S, SE, SVE, or Sport — does not affect which catalytic converter is fitted; what matters is the engine code and the model year, as the exhaust system follows the drivetrain rather than the specification level. Two Primeras of the same generation and same engine but different trims will use the same cat. When speaking to a breaker, quote your engine code and registration rather than your trim name.

Both a 2002 and a 2004 Primera fall within the P12 generation (2002–2008), so there is a reasonable chance of compatibility if the engine codes match, but catalytic converter interchange specifics are strong confirm-with-breaker territory even within a generation. Give the breaker both registrations and your engine code so they can verify the part number rather than relying on the year alone.

No — diesel and petrol emissions systems are fundamentally different. Petrol engines use a three-way catalytic converter to treat hydrocarbons, carbon monoxide, and nitrogen oxides, while diesel variants use different aftertreatment technology entirely. Always make sure the cat you are sourcing comes from a petrol-engined Primera with the same engine code as your own vehicle.

The P11 Primera received a facelift in 1999, and while both sit within the same broad generation (1996–2002), there can be differences in engine tune and exhaust specification between pre- and post-facelift cars that affect cat compatibility. Because catalytic converter interchange across a facelift boundary is not straightforward to confirm without checking part numbers, this is firmly confirm-with-breaker territory — give them your engine code and registration and ask them to verify against their donor car before agreeing a sale.
