A single Dinan iridium spark plug in heat range 9, measuring 12mm thread by 26.5mm reach with a 14mm flat seat. Sold individually, so order the number of cylinders you are servicing.

Verified fitment: across the Mini range this covers 2007-2024 Mini Cooper Base, 2014-2024 Cooper S, 2015-2024 John Cooper Works and the 2021 JCW GP, 2016-2024 Clubman in Base, S, S ALL4 and JCW ALL4, and 2011-2024 Countryman in Base, ALL4, S, S ALL4, S E ALL4 and JCW ALL4. The same plug is catalogued for a long list of modern BMW models and the Toyota GR Supra.

A colder heat range is the usual move once an engine is making more than it left the factory with, because the standard plug is specified for standard cylinder temperatures. Getting the seat type and reach right matters as much as the heat range, which is why the dimensions are stated plainly here.

Running more boost than stock and unsure whether heat range 9 is a step too far? Rev Auto Club will talk it through with you before you order a full set.
