4 X NGK Spark Plugs - Ideal for cars with reduced supercharger pulleys as they run colder than stock.
Can also be used on standard MINI One, Cooper and Cooper S without any issues.
We run these same plugs in our 'Old Red' Race MINI - Currently the Quickest and Fastes MINI over a 1/4 mile in the world, this W11 engine has made over 600HP on a dyno
Recommended Spark Plug gap is 25 thou / 0.6mm
