I am running a rover coupe turbo with a few mods:
boost at 13psi, fse boost valve
a friend suggested I should use cooler sparkplugs than standard, but he doesn't know why, just that someone else is running them on a modded turbo car.
I am having a few jerking problems when accelerating, so I am going to replace the plugs, ht leads, distributor cap and rotor arm anyway, the plugs have done about 12k, so should I get cooler plugs?
is there any good reason for running them?
how do you know if you should?
