Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Original Equipment Ignition Plug for BMW N43 N51 N53 Engines | Part No. 12120038349
Give your BMW a crisp, clean spark and restore smooth running with this factory-spec ignition plug, part number 12120038349. Built to BMW’s own specification for the N43, N51 and N53 petrol engines, it delivers reliable cold starts, stable combustion and long service life. Ideal for routine maintenance or curing misfire issues on popular 1 Series, 3 Series, 5 Series and 6 Series models listed below.
Why this OE ignition plug is the right choice
- True BMW part for perfect fit and the correct heat rating
- Helps reduce hesitation and stumble under load to recover lost performance
- Consistent spark for steady idle, sharper throttle response and cleaner emissions
- Designed to work seamlessly with factory coils and engine management
We run these plugs on our own cars and customer vehicles at MJ Modifications and feedback has been excellent. Owners report smoother idle, fewer misfire faults and improved drivability after fitting a fresh set.
Signs your plugs are due
- Rough idle or intermittent misfires
- Flat spots and sluggish acceleration
- Hard starting, especially when cold
- Higher fuel consumption compared to normal
If your N43, N51 or N53 shows any of the above, replacing the plugs is a proven first step before chasing sensors or coils.
