Second Hand Vauxhall Adam Exhaust Manifold

The exhaust manifold is the cast component that collects exhaust gases from each cylinder and feeds them into the rest of the exhaust system, and yes, every Vauxhall Adam has one — it was sold exclusively with petrol engines, so there is no diesel variant to complicate things. The Adam was produced from 2013 to 2019 as a single generation with no major architectural change to its engine range, meaning all cars share the same basic layout. The engines fitted across the range were small-capacity petrols (1.0-litre turbocharged and 1.2/1.4-litre naturally aspirated units), and each engine code has its own manifold, so matching the engine code is the critical first step when sourcing a used one.

Engine code matters a great deal here — the 1.0-litre turbocharged unit (commonly coded B10XFL or B10XFT depending on state of tune) has a turbocharger mounted very close to or integrated with the manifold assembly, so it is a completely different item from the manifolds used on the 1.2-litre (A12XER) or 1.4-litre (A14NET/A14XEL) naturally aspirated engines. Fitting the wrong manifold is not simply a case of drilling extra holes — the flanges, port spacing and turbo mounting points differ between families. Always check your engine code on the cam cover or via your V5C before contacting a breaker, and give that code to the dismantler so they can pull the correct unit.

The Vauxhall Adam ran from 2013 through to 2019 as a single generation without a major structural facelift that altered the engine range, so on paper a manifold from the same engine code should share the same basic design throughout production. However, emissions legislation tightened across this period — Euro 5 applied to early cars and Euro 6 was phased in from around 2015 onwards — and emissions-era changes can affect the exhaust and catalyst assembly in ways that make components from the wrong era incompatible or problematic at MOT. If you are crossing that approximate 2015 Euro 5/Euro 6 boundary, confirm with the breaker that the donor car's engine code and registration year match yours before buying.

Trim level makes no difference whatsoever to the exhaust manifold — JAM, Slam, Glam, Rocks, and any other Adam trim designation refer purely to cosmetic and equipment specifications, not to the engine or exhaust architecture. What matters solely is the engine code fitted to your specific car, which you can find on the cam cover or confirmed via your registration through the breaker. Two Adam Slams with different engines will need different manifolds, while a Slam and a Glam with identical engine codes will need exactly the same one.

Give the breaker your engine code (not just the engine size, as the 1.0-litre turbo has more than one tune variant), your registration year, and ideally your VIN so they can verify the emissions era of the donor vehicle against yours. Check whether the manifold is sold with or without the oxygen sensor(s) and whether the turbocharger is included on turbocharged units, as breakers sometimes split these — missing sensors or a seized turbo flange can turn a cheap part into an expensive job. The question of whether any catalyst section integrated into or immediately downstream of the manifold will pass your MOT is strong confirm-with-breaker territory, so raise it explicitly rather than assuming.

The Adam shares its engine family with the Corsa of the same era, and on paper engines such as the A14NET and 1.0-litre turbo units appear across both model lines, which means manifolds can sometimes interchange where the engine code, year, and emissions era all match. However, bay packaging differences between the Adam and Corsa mean ancillary routing and heat-shield fitment can differ even when the core manifold flange pattern is identical, so a part that bolts on may still foul other components. Confirm with the breaker that the donor vehicle's engine code and registration year match yours exactly, and ask whether they have successfully supplied that cross-model combination before.
