Mazda CX-5 Coil Pack Replacement Parts

It depends entirely on the engine. The CX-5 has always been offered with petrol engines, and petrol engines do use ignition coils — however, on most modern petrol engines (including those in the CX-5) each cylinder has its own individual coil-on-plug unit rather than a single combined coil pack as found on older cars, so you may see these listed as individual coils or a set rather than a single 'coil pack'. The diesel engines fitted to the CX-5 (the 2.2 Skyactiv-D) use compression ignition and have no ignition coils whatsoever, so if you have a diesel CX-5 you do not need this part at all. Confirm exactly what you need with the breaker once you have your engine code to hand.

The CX-5 ran in its first generation (Mk1) from 2012 to 2017, with the second generation (Mk2) arriving for 2017–2018 onwards, so a 2014 car is Mk1 and a 2018 car is Mk2 — these are different generations with different engine architectures. Even where the petrol engine displacement looks similar across the two generations, the internal design and associated ignition components changed, so coils from a Mk1 are unlikely to be a straight swap onto a Mk2. Always confirm cross-generation compatibility with the breaker, quoting the engine code from both vehicles.

Trim level makes no difference to ignition coil fitment on the CX-5 — Sport, SE, SE-L, and GT Sport trims are all fitted with the same engine variants, and it is the engine code rather than the badge that determines which coil is correct. A coil from an SE-L and a coil from a Sport with the same engine code and from the same generation should be the same part. The only thing worth noting is that higher trims occasionally introduced different engine options at different points in the model's life, so always verify the engine code rather than relying on trim name alone.

The engine code is the single most important detail for this part — for the Mk1 CX-5 the 2.0-litre petrol carries the Skyactiv-G 2.0 designation (engine code PE) and the 2.5-litre petrol the Skyactiv-G 2.5 (engine code PY), and these use different coils, so quoting the wrong one could mean an incompatible part. You can find your engine code on your V5C logbook or by running a VIN check. Give this code directly to the breaker alongside your registration and they can match the correct coil for your car.

The Mk1 CX-5 received a facelift in 2015, and while the core Skyactiv-G petrol engines carried over, there can be ancillary and mounting changes mid-production that are not always obvious from the outside. For the ignition coils themselves, the engine code is the key check, but whether any minor production changes affected the coil specification between pre- and post-facelift cars is something you should confirm with the breaker against your specific registration rather than assume. A good breaker will be able to cross-reference your reg to make sure the coil they have matches your exact build.

Because the CX-5 petrol engines use individual coil-on-plug units — one per cylinder — you can buy and replace just a single faulty coil rather than a full set, which makes sourcing from a breaker a cost-effective option. That said, if your engine has higher mileage it is worth asking the breaker whether they can supply a matched set from the same donor vehicle, as coils of similar age and wear can be preferable to mixing old and new. Confirm the quantity you need with your mechanic before ordering, and always match by engine code.
