Genuine BMW High Power Spark Plug Set for E84 E89 F06 — Overview

These are the OEM spark plugs straight from BMW, part number 12120039664, sold as a full set of four. They're spec'd for the N20 and N26 four-cylinder turbo engines found in the E84 X1, E89 Z4, and F06 Gran Coupe applications - so if you're running one of those chassis, this is exactly what the factory put in and what BMW wants back in there on the next service interval. No guessing on heat range, electrode gap, or thread pitch compatibility.

I'd pick these over aftermarket plugs when the car is still under warranty, when you've had ignition-related misfires and want to eliminate variables, or when you just don't want to research whether a NGK or Bosch equivalent actually crosses correctly for your specific build date. The N20 in particular can be fussy about plug condition given the direct injection and the boost - fresh OEM plugs make a noticeable difference in cold start smoothness and idle quality when the old ones are worn out. At around 40-60k miles these should be on your radar regardless.
