Cheap BMW 7 Series Glow Plugs

Only diesel variants of the BMW 7 Series have glow plugs — petrol engines do not use them, so if your car is a petrol 730i, 740i, 750i or similar, this part does not apply to your vehicle. Diesel models such as the 730d, 740d and 750d do have glow plugs, one per cylinder, to aid cold starting. If you have a petrol 7 Series and are chasing a cold-start or misfiring problem, the part you are likely looking for is an ignition coil or spark plug instead.

These two cars sit in different generations — the E65/E66 generation ran from 2001 to 2008, the F01/F02 generation from 2008 to 2015 — so a 2010 and a 2014 730d are actually both F01 generation cars and share the same basic platform. However, fitment of the glow plugs themselves is determined primarily by the engine code, not the model year, so you should match the engine code on your V5 or via a VIN check against the donor car's code before buying. Confirm compatibility with the breaker against your registration to be certain.

Yes, these are completely different generations with different diesel engine families, so the glow plugs from an E65 730d will not be a straightforward swap into an F01 730d. The engine codes changed between generations, and glow plug specification — thread size, voltage rating and tip design — follows the engine code above everything else. Always quote your exact engine code to the breaker rather than just the year or badge.

No — SE, M Sport, and any other trim level fitted to the 7 Series are cosmetic and equipment differences only and have no effect on glow plug fitment whatsoever. What determines the correct glow plug is your engine code, the diesel variant you have, and the generation of the car. You can safely ignore trim level entirely when sourcing this part.

No, the G11/G12 generation that launched in 2015 uses different diesel engine families from the outgoing F01/F02 (2008–2015), so glow plugs are not interchangeable between these two generations. As always, the engine code is the critical detail — check it on your V5 or through a VIN check and provide it to the breaker when requesting a quote. Do not assume fitment based on badge or engine size alone.

Diesel BMW 7 Series engines have one glow plug per cylinder — six-cylinder models like the 730d need six plugs, and eight-cylinder diesels like the 740d need eight. Breakers selling used parts will often supply them individually, but it is worth asking whether a matched set from the same engine is available, as plugs from the same donor car will have worn evenly. Confirm the quantity and engine code with the breaker against your registration before ordering.
