A large number of Japanese minis seem to have a lot of after market earthing kit on them and I am curious why? There are engine bay earthing kits, battery power up (gimmicks) and earthed ignition leads..
My 98 Cooper came from Japan with ignition leads that each have a separate earth strap that connects to the heads bolts. They are labelled 'Sports Delta' and have a Japanese telephone number on them. The only thing I can find on them is that they are sold by Turtle Trading (and a number of other outlets) in Japan. They have been partnered with Iridium BPR6 plugs.
As the car has a bit of a flat spot off idle, I am looking to change the plugs to non Iridium BPR6 (three look the same, number 3 tip looks a touch brown). Am considering changing the leads but curious if anyone could see a benefit in earthed leads?
