Special kit that includes 4 replacement spark plugs and special 5" deep socket to make installation simple and painless. The NGK plugs are rated a step cooler than stock in the MINI Cooper S .

Fits following models with the Supercharger Pulley Upgrade:

2002-2006 R53 MINI Cooper S Hatchback
2005-2008 R52 MINI Cooper S Convertible

The tapered ground electrode of the spark plug increases flame kernel expansion, while the superior heat range design is ideally suited to the demands of high performance MINI Cooper S with the pulley upgrade. Spark plugs come pre-gapped, but should be checked for .035" gap before installation. Sold individually.

Use this six point 5/8" deep well spark plug socket to reach the spark plugs on your MINI. 3/8" drive, 5" long, and equipped with the expected rubber insert.

This tool will also work on cars with high performance camshafts where the spark plug tubes have been properly "clearanced" to eliminate lobe peak interference.

Note: Socket may be chrome OR black finish depending on supply.

Select from:

NGK Iridium IX high performance spark plugs with a .6mm iridium center electrode for superior ignitability without sacrificing durability.
