Used Mazda CX-3 Exhaust Manifold

Yes, all petrol and diesel engine variants of the Mazda CX-3 (2015 onwards) have an exhaust manifold — it is the cast component that collects exhaust gases from the cylinder head and routes them towards the catalytic converter and the rest of the exhaust system. The CX-3 was never sold with a turbocharged engine in the UK, so there is no turbocharger between the manifold and the engine to complicate matters, but the manifold design still varies by engine code and fuel type. Make sure you identify your engine code from the VIN plate or service documents before searching.

The Mazda CX-3 received a facelift for the 2018 model year, and while the engine line-up remained broadly similar, there were updates to emissions systems across that boundary that can affect exhaust components. The safest approach is to match the engine code exactly rather than assume a pre-2018 manifold will drop straight onto a post-2018 car, and you should confirm compatibility with the breaker against your specific registration before buying. Naming the boundary is easy — 2015–2018 pre-facelift, 2018 onwards facelift — but whether a specific manifold crosses it without issue is something only the breaker can verify against your reg.

Engine code is the single most important factor for exhaust manifold fitment on the CX-3 — the year alone is not enough. The CX-3 was offered with a 2.0-litre petrol (engine code PE) and a 1.5-litre diesel (engine code S5), and the manifolds for these engines are completely different castings that will not interchange. Always quote your engine code to the breaker alongside your registration number.

Trim level has no effect on exhaust manifold fitment for the Mazda CX-3 — the manifold is determined by the engine, not whether the car is an SE, Sport, or GT Sport. You may find that breakers describe parts from higher-spec cars, but provided the engine code matches yours, the trim is irrelevant to this particular component. The only thing worth noting is that a manifold pulled from any trim level may come with minor heat shielding differences, so check that with the breaker if your existing heat shield is reusable.

No — the exhaust manifold on the CX-3 is determined by the engine code and not by the drivetrain layout (FWD or AWD). Both drive configurations used the same engine families, so the manifold itself is the same component regardless of whether your car is a two-wheel-drive or i-Activ AWD model. Confirm your engine code with the breaker and that covers the key fitment variable for this part.

Yes, emissions era is worth raising with the breaker for a diesel CX-3 manifold, because Euro 5 and Euro 6 engines can have differences in exhaust architecture that affect how components upstream of the DPF are designed. The CX-3 1.5-litre diesel (S5 engine) was sold across both emissions eras during its UK production run, and a manifold from the wrong era may not seat or seal correctly against the downstream emissions hardware. Anything to do with DPF compatibility specifically is strong confirm-with-breaker territory — give the breaker your registration and ask them to verify against your exact engine code and emissions specification.
