Is anyone using NGK Iridium plugs in their four wheel drives?I
currently use them on in my 240SX and when first installed gave a very
small boost of power with a stock ignition.I want to use a MSD Ignition
System and Iridium due to the longer lifespan they seem to offer.I just
dont know how well they work off road.
