Is the part number for the NGK TRix iridium plugs #3689?
So 3689 NGK iridium will fit our L67?
I got the 3689 NGK iridiums, so the wrong damn ones. F***
Where Do I find the NGK-gfys? Their 2 heat ranges colder righr?
They're saying that the 3689 ngkix fit the LS4 motors
I tried autozone, they they dont sell them 2 heat ranges colder
