Mazda 3 Camshaft Replacement Parts

This crosses a significant generation boundary: the second-generation Mazda 3 (BL) ran from 2009 to 2013, while the third-generation (BM) launched in 2013. Even if the engine displacement looks the same, the engine architecture changed between these generations, so a camshaft from a BL-generation car is very unlikely to suit a BM-generation car. Confirm the engine code from your V5 or a VIN check and give it to the breaker before ordering.

Both years sit within the third-generation Mazda 3 (BM/BN, 2013 to 2018), though a facelift arrived around 2016 and the fourth-generation (BP) launched for 2019. If your 2019 car is a BP-generation model, the engine family differs from the BM/BN, making the camshaft very unlikely to interchange. Check your engine code on the V5 and confirm with the breaker against your registration.

Trim level makes no difference whatsoever to camshaft fitment — SE, Sport, Sport Nav, and GT Sport are all badge and equipment distinctions that have no bearing on the engine internals. What matters is your engine code, fuel type, and the generation of the car, all of which can be found on your V5 or via a VIN check. Give the breaker your engine code and they will match the correct camshaft regardless of which trim your car is.

Yes, fuel type is critical — petrol and diesel engines are entirely different units and their camshafts are not interchangeable under any circumstances. Within petrol variants there were also different displacements and engine codes across the Mazda 3 generations, so even two petrol cars can need different camshafts. Always quote your exact engine code from the V5 alongside petrol or diesel to get the right part.

A 2008 Mazda 3 is a first-generation BK model, which ran from 2003 to 2009. Camshafts within the BK generation can potentially interchange where the engine code matches exactly, but there were running changes during production, so confirm the engine code with the breaker rather than assuming year alone is enough. Supply your registration or V5 engine code when requesting a quote to avoid ordering the wrong part.

In most cases the camshaft itself is determined by the engine code rather than the gearbox type, so a manual and automatic Mazda 3 with the same engine code will typically use the same camshaft. However, gearbox type is still worth mentioning to the breaker because it can occasionally influence ancillary components fitted around the engine. Give the breaker your full engine code, fuel type, and gearbox type to let them confirm fitment against your registration.
