Fitment questions
Will a cylinder head from an earlier Alfa Romeo 155 fit my later one?
The Alfa Romeo 155 was produced from 1992 to 1998 as a single generation, but there were running production changes throughout that period that can affect whether a cylinder head swaps cleanly across different build years. The engine code is the most reliable guide here — if both cars share the same engine code (found on your V5 or via a VIN check), the head is far more likely to be compatible than if you're simply matching by year. Confirm with the breaker against your registration before buying, as ancillary and mounting details may have changed mid-run.
Does a cylinder head from a 155 Twin Spark fit a 155 with the older single-spark engine?
No — the Twin Spark engine has a fundamentally different head design with two spark plugs per cylinder, so it is not interchangeable with the earlier single-plug units even if the displacement looks similar on paper. Fuel type and engine code are what determine fitment here, not the model name or year badge. Always give the breaker your exact engine code so they can match the correct head.
Does the trim level affect which cylinder head I need — for example, does a 155 Ti need a different head to a standard 155?
Trim level does not affect cylinder head fitment on the 155 — the head follows the engine, not the badge or equipment level. A Ti and a base-model 155 sharing the same engine code will use the same head, though you may find minor cosmetic or ancillary differences on the used part depending on its source. Focus on matching the engine code rather than the trim name.
I have a 155 V6 — can I use a cylinder head from any other V6 155?
The V6 155 used the Busso V6 engine, and if the engine codes match, a head from another V6 155 is a promising starting point. However, confirm with the breaker against your registration, as there were detail changes across the production run that could affect ancillary or mounting compatibility. The engine code on your V5 or from a VIN check is the single most useful piece of information you can give a breaker.
Does it matter whether my 155 is petrol or diesel when sourcing a cylinder head?
Yes, absolutely — petrol and diesel cylinder heads are completely different in design and are not interchangeable under any circumstances. Make sure you specify your fuel type clearly alongside the engine code when contacting a breaker, as both details are needed to identify the right part. Getting the engine code from your V5 or a VIN check removes any ambiguity.
Will a cylinder head from a 155 fit an Alfa Romeo 145 or 146 with the same engine?
If the engine codes genuinely match across those models, there is a reasonable chance the head itself is the same unit, as Alfa Romeo used shared engines across the 145, 146, and 155 ranges during the same period. However, ancillary fittings, sensors, and mounting points can differ between applications, so this is not something to assume without checking. Put the question directly to the breaker with both registrations or both engine codes so they can advise properly.
