OEM Part Number: confirm via VIN — engine mount (aftermarket) Febest MZM-KERH / Kavo EEM-4679

Accuracy note: Covers the Mazda 3 (BM 2013-2019) as listed in the UK aftermarket catalogues. Engine mounts are sold by position (left, right, front, rear, upper, lower), and the right one depends on the engine, the gearbox (manual, automatic or dual-clutch) and the trim. The references below are examples from the UK aftermarket catalogue for the engines checked on this generation, so match your own engine code and gearbox before ordering; the carmaker's own numbers are not quoted in those listings, so check the genuine mount against your VIN if you want a guaranteed match.

Engine Mount — Left (aftermarket)	Kavo EEM-4679, Maxgear 40-0670
Engine Mount — Rear (aftermarket)	Original Imperium 610276, Tedgum TED49039
Engine Mount — Right front (aftermarket)	Maxgear 40-0819, Febest MZM-KERH
Genuine (OE) number	Not quoted in the catalogue listings — mounts differ by engine and gearbox, so order the genuine ones against your VIN
Fitment notes	The listing above shows examples for the engines checked; petrol, diesel, manual and automatic versions often use different mounts, and cars usually have more than one mount.

A Genuinely Useful, Free Diagnostic Test Worth Trying — Mazda 3 Engine Mount

If you're chasing a vibration and want to confirm whether an engine mount is genuinely responsible, this is worth trying: with the car stationary and the gear selector in Park, press the accelerator pedal and watch the engine visually — if it's a genuine mount issue, you'll typically see noticeably more engine movement than normal. If there's no unusual shaking while stationary, the vibration may actually be coming from the wheels, suspension, or transmission instead.

A genuinely distinctive, real cross-check worth knowing about before committing to mount replacement: one documented case on a related model saw an owner chase what sounded exactly like an engine mount clunk for well over a year, before discovering the actual cause was a steering column coupler needing nothing more than an eighth of a turn adjustment.

It's also worth knowing that persistent, hard-to-pin-down vibration has been documented surviving multiple new sets of wheels and tyres and proper road force balancing in some genuinely frustrating, real cases.

Mazda 3 Engine Mount: What It Does

Engine mounts secure the engine and transmission to the chassis while absorbing vibration and movement, preventing that vibration from transferring directly into the cabin. Most versions of the 3 use several mounts working together — typically at least one on each side of the engine plus a torque mount — and a single failed mount can throw off the whole assembly's balance.
