Cheap BMW Z4 Coil Pack

The BMW Z4 has only ever been sold with petrol engines, so yes, every variant uses coil-on-plug ignition coils — what are commonly called a coil pack. Diesel Z4s do not exist, so if you own a Z4 you will definitely need an ignition coil rather than a glow plug or injector. The number of coils you need matches your cylinder count — four coils for a four-cylinder engine, six for an inline-six.

The E85/E86 generation ran from 2003 to 2009, and the E89 generation replaced it from 2009 onwards, so a 2007 car is E85 and a 2010 car is E89 — these are entirely different platforms with different engines. Fitment depends primarily on the engine code, so even if two cars share a similar displacement badge (for example both badged 2.5i), the engine codes may differ across that generational boundary. Check your engine code on your V5 or a VIN check and give it to the breaker before ordering.

No, the trim level makes no difference to ignition coil fitment on the Z4 — SE, Sport, and M Sport are cosmetic and equipment packages, not mechanical variants. What determines the correct coil pack is the engine code, not the badge or trim. Quote the engine code to the breaker and trim level can be ignored entirely for this part.

The four-cylinder 2.0i engines use four individual coil-on-plug coils, one per cylinder, so you may need to replace one or all four. Within the E89 generation (2009–2016), 2.0i cars sharing the same engine code are the most likely candidates to cross-fit, but confirm the exact engine code with the breaker against your registration before buying, as there were updates during that production run.

BMW used the same family of engines across multiple models, so if the engine codes genuinely match, the coil-on-plug unit is often the same part. However, ancillary fitment and connector types can vary even within an engine family depending on production date, so this is worth confirming with the breaker against your specific registration rather than assuming a match on badge or displacement alone. The engine code is the key detail to give the breaker, and they can cross-reference from there.

The Z4 M (E85 generation, sold in the UK from around 2006) used the S54 inline-six engine, which is a different unit from the engines in standard Z4 models, so the coil packs are not interchangeable. Always source coil packs specifically matched to the S54 engine code if you own the M variant, and confirm with the breaker against your registration to ensure the part is correct.
