Cheap BMW 1 Series Exhaust Manifold

Yes, the generation matters significantly. The BMW 1 Series ran as the E87/E81 from 2004 to 2011, then moved to the F20/F21 from 2011 to 2019, with a facelift in 2015. These generations use different engines and different exhaust manifold designs, so a manifold from an E87 will not transfer to an F20 — always match the part to your exact generation and engine code.

Yes, petrol and diesel engines have entirely separate exhaust manifold designs and they are not interchangeable. On diesel variants the manifold is closely integrated with the turbocharger and emissions equipment, whereas petrol setups differ in port arrangement and mounting. Always tell the breaker your exact fuel type and engine code to ensure you get the right manifold.

It can matter, particularly on diesel engines where the manifold design is tied to the emissions system architecture of that era — Euro 6 engines (broadly from 2014 onwards on the 1 Series) can have different manifold geometry and turbo integration compared with earlier Euro 5 units. Fitting a manifold from the wrong emissions era may cause running problems or an MOT failure. Confirm the emissions standard and engine code with the breaker before buying.

For the exhaust manifold, trim level does not affect fitment — what matters is the engine code, not whether the car is badged SE, Sport, M Sport, or M140i. The M Sport trim is a cosmetic and chassis package and does not alter the engine's exhaust manifold. Match the part to your engine code and the breaker will be able to cross-reference this against your registration.

Both a 2013 and a 2016 BMW 1 Series fall within the F20/F21 generation (2011–2019), but 2015 brought a facelift that included engine updates on several variants, meaning some engine codes changed at that boundary. Whether a pre-facelift manifold crosses over to a post-facelift car depends on whether both cars share the same engine code — confirm this with the breaker against both registrations before purchasing.

All BMW 1 Series engines — both petrol and diesel, naturally aspirated and turbocharged — have an exhaust manifold, as it is a fundamental component that collects exhaust gases from the cylinder head and routes them onwards. On turbocharged engines, which covers the vast majority of 1 Series variants sold in the UK, the manifold is often integrated with or bolted directly to the turbocharger. Make sure to give the breaker your full engine code so they can supply the correct unit for your specific engine.
