Alfa Romeo Brera Cylinder Head Replacement Parts

The Brera ran as a single generation from 2005 to 2010, so there is no major generational boundary between a 2007 and 2010 car — but fitment of a used cylinder head depends almost entirely on matching the engine code, not the year alone. Locate your engine code from your V5 or a VIN check and make sure the breaker can confirm the donor car shares the same code. There can be running production changes to ancillary fittings or mounting points across those years, so always confirm the specifics against your registration with the breaker before buying.

No — the 2.2 JTS (engine code 939A5) is a four-cylinder unit and the 3.2 V6 (engine code 939A0) is an entirely different engine, so the cylinder heads are not interchangeable at all. Always match the cylinder head to your exact engine code rather than going by displacement or model year. Your engine code is the single most reliable detail to give any breaker when quoting for this part.

The 2.4 JTDm (engine code 939A3) was used throughout the Brera's 2005–2010 production run, and heads from the same engine code are your starting point for compatibility. However, there can be mid-production changes to ancillary or mounting details, so confirm with the breaker that the donor vehicle's head matches your specific registration rather than assuming any 2.4 JTDm head will drop straight in. Providing your engine code and registration to the breaker is the safest way to get an accurate match.

Trim level does not affect cylinder head fitment — what matters is the engine code, and the Brera S used the same 3.2 V6 engine as found in the wider Brera range rather than a mechanically unique unit. You may find cosmetic or interior differences between a Brera S and a standard car, but these have no bearing on the cylinder head. Give the breaker your engine code and registration and they can confirm the right head regardless of trim designation.

The Brera and 159 do share engine families, including the 2.2 JTS, 2.4 JTDm and 3.2 V6, because both are based on the same platform, so a head with a matching engine code is worth investigating. That said, ancillary fittings, sensors or minor casting differences can vary between applications even where the engine code looks identical, so you should not assume a 159 head will be a direct swap without checking. Route this specific cross-model question to the breaker and give them both vehicle registrations so they can compare the parts before you commit.

A remap does not change which cylinder head you need; the correct head is still determined by your engine code. However, if the head needs to be paired with any engine management hardware or the ECU has been modified as part of the remap, there may be coding considerations — confirm this with the breaker against your registration rather than assuming a straight swap. In most cases a used head from the correct engine code will be compatible, but it is worth being upfront with the breaker about the remap so they can advise accordingly.
