Second Hand Alfa Romeo Spider Inlet Manifold

Yes – all variants of the Alfa Romeo Spider are petrol-engined, and every petrol engine uses an inlet manifold to feed the air-fuel charge into the cylinders, so the part does exist on this model across all generations. The design and fitting points differ significantly between the 105-series Spider (1966–1993), the 916-series Spider (1995–2005), and the 939-series Spider (2006–2011), so you need to match to the correct generation first. Within each generation there are further differences tied to the specific engine fitted, so the engine code from your V5 or a VIN check is the most important detail you can give a breaker.

No – these are entirely different generations with unrelated engine families; the 916 used engines such as the Twin Spark units while the 939 moved to a completely different range including the 2.2 JTS and 3.2 V6, and the inlet manifolds are not interchangeable between them. Always match the part to your generation and, within that, to your exact engine code. Confirm the specific casting and port configuration with the breaker against your registration before buying.

Yes, significantly – a four-cylinder 2.2 JTS and a six-cylinder 3.2 V6 are fundamentally different engines with entirely different inlet manifold designs, port counts, and mounting arrangements, so they share no manifold parts. The engine code stamped on the block (and listed on your V5 or via a VIN check) will confirm exactly which unit you have and is the detail breakers need to pull the correct part. Never assume a manifold from a different-displacement Spider will fit yours even if the model year looks close.

Trim level alone does not determine inlet manifold fitment – what matters is the engine code, which can sometimes vary between trim grades if different engines were offered. On the 939-series Spider the Q4 designation indicated four-wheel drive paired with the 3.2 V6, while Lusso was available across engine choices, so the manifolds differ by engine, not by the Lusso or Q4 badge itself. Give the breaker your engine code rather than just your trim name and they can match the correct manifold to your car.

The 916 Spider received a facelift from around 2003 onwards, and while the core engine families carried over, there can be ancillary and mounting changes mid-production that affect manifold compatibility. You should not assume a pre-facelift manifold swaps straight onto a post-facelift car without checking; confirm fitment against your specific registration with the breaker. Providing your engine code – not just the year – gives the breaker the best chance of supplying the right part first time.

No – the 105-series Spider used the classic twin-cam engine family that is completely unrelated to the engines in either the 916 or 939-series cars, and the inlet manifolds are entirely incompatible in design, mounting, and porting. The 105-series ran a long production life during which the engine itself evolved (including carburetor to fuel-injection changes), so even within that generation you need to match the manifold carefully to your specific engine code and specification. A breaker will need your engine code and ideally your registration to confirm the right unit.
