Alfa Romeo 155 Inlet Manifold Replacement Parts

Yes, every Alfa Romeo 155 has an inlet manifold — it is a fundamental part of any petrol or diesel engine's air and fuel delivery system, so all engine variants of the 155 were fitted with one. However, the manifold design varies significantly between engine types, so a petrol manifold will not interchange with a diesel unit and vice versa. Always specify your fuel type and engine code when requesting a quote from a breaker.

The Alfa Romeo 155 ran from 1992 to 1998, with a facelift in 1995 that brought some mechanical and trim updates, so the year of the donor car does matter. Fitment is primarily governed by engine code rather than model year alone, and two cars from either side of the 1995 facelift may share the same engine code and therefore the same manifold. However, ancillary fittings and mounting points can change mid-production, so confirm compatibility against your specific registration with the breaker before purchasing.

Yes — the engine code is the single most important detail for matching an inlet manifold on the Alfa Romeo 155, overriding year and trim in almost every case. Two 155s from different years but sharing the same engine code are far more likely to use the same manifold than two same-year cars with different engines. Your engine code is printed on your V5C or can be confirmed via a VIN check, and supplying it to the breaker will give you the most accurate quote.

Absolutely — the Twin Spark four-cylinder engines and the 2.5 V6 engine are entirely different units with completely different inlet manifold designs that will not interchange. The manifold for the V6 is notably larger and differently configured to suit its six-cylinder layout, while the Twin Spark units each have their own specific manifold matched to that engine's air management system. Always confirm your exact engine code with the breaker rather than relying on the badge or cylinder count alone.

No — trim level has no bearing on inlet manifold fitment for the 155. Trims such as the base, Cloverleaf, or Q4 variants used different engines, and it is the engine code attached to those variants that determines the correct manifold, not the trim designation itself. When contacting a breaker, focus on your engine code and fuel type rather than the trim name.

The Q4 used a turbocharged four-cylinder engine, whereas the naturally aspirated 2.0 Twin Spark is a different unit, and manifolds from these two engines are not the same design. The turbo engine requires a manifold suited to forced induction air delivery, while the naturally aspirated unit uses a different configuration entirely. Confirm both engine codes with your breaker to establish whether any crossover exists, and never assume fitment based on displacement alone.
