I m after some blue performance HT leads but they all seem to be costly for the mini unlike other car makes .does anyone know of any

It seems to be the opinion of a lot of people that changing spark-plug leads provides no
performance benefit, so I would suggest looking for some cosmetic blue covering you
can add to your normal leads.

MINI also sells blue spark plug leads. High performance ignition parts will only show benefit on motors with very high boost levels and/or nitrous.
