Cheap Vauxhall Cavalier Inlet Manifold

Yes, every Cavalier engine — whether petrol or diesel — has an inlet manifold, as it is a fundamental part of any internal combustion engine that directs the air-fuel mixture (or air, on diesels) into the cylinders. There is no drivetrain or body-style variant of the Cavalier that lacks one. So whatever engine your Cavalier runs, a replacement inlet manifold exists for it.

Almost certainly not — the Cavalier Mk2 ran from 1981 to 1988 and the Mk3 from 1988 to 1995, and the two generations used largely different engine families with different manifold designs. Even where a similar engine code carried across, ancillary and mounting details can differ between generations, so you should confirm compatibility with the breaker against your exact registration and engine code rather than assuming a straight swap.

Yes — the engine code is the single most important detail, because Vauxhall fitted several different engines across the Cavalier range and the manifold is matched to the specific engine, not to the model year or body style. You can find your engine code on your V5 registration document or through a VIN check, and giving it to the breaker will save a lot of back-and-forth. Year helps narrow things down within a generation, but the engine code is what actually determines whether a manifold will bolt on.

No — trim level has no bearing on inlet manifold fitment at all. Whether your Cavalier is a base-spec L or a sportier SRi, the manifold is determined entirely by the engine fitted, not by the badge on the back. Do bear in mind that some trim levels were more commonly paired with certain engines, so if you tell the breaker your trim as well as your engine code it gives them useful context, but the engine code is what counts.

The Cavalier Mk3 ran from 1988 to 1995 and received a facelift in 1992, but the core engine lineup remained broadly similar across both phases of the generation. That said, ancillary fittings and manifold mountings can change mid-production without obvious external signs, so whether a pre-1992 and a post-1992 unit are a straight swap is something you should confirm with the breaker against your registration and engine code rather than assume.

Yes — petrol and diesel Cavalier manifolds are completely different and not interchangeable, as they manage different things: petrol manifolds handle the air-fuel charge, while diesel manifolds deal with air only and are designed around very different port geometry and pressures. Always tell the breaker whether your car is petrol or diesel, along with the engine code, to make sure you are quoted the correct part for your vehicle.
