NGK iridium IX Spark plugs feature an iridium plated centre electrode, and require less energy to discharge than a platinum or copper plug. This means more potential voltage is available at the coil, and more voltage available for ignition.
I stock two variants.
BKR6EIX-11 features OEM heat range 6 and a 1.1mm gap. This is ideal for NA and for lightly modified TT motors.
BKR7EIX features a colder heat range 7 and a tighter .8mm gap. This is ideal for boosted TT motors.
Purchase is per set of six plugs, and includes delivery within AUS only.
