Fast wearing NGK Iridiums - 09/07/2010 14:44
Has anybody else noticed the NGK (7's) Iridiums wearing quite fast..?
I thought they would last next to forever.
I've had mine in for a year or so (ca 15000km's) and especially the second plug has worn badly on the outer piece (not the thin Iridium pin), but the others were a bit rounded off too.
One could also wonder if this affects the performance much as long as the gap is correct..?
