As long as IK/KH/Q/W/T16/20L (Original 1.1mm) once is gapped to 0.8mm => more power and performance can be expected (immediate effect after installed).
Measurement of plug gapping to 0.8mm will be shown to buyer during order collection.
Just wanted to ask those of you who've removed your speed limiters, are you guys still using your stock speedo or have you changed to an aftermarket speedo?
