Ok well my plugs in my car now are part number ZFR5GP... my new ones that I just bought are ZFR5J-11 for 95 Z6 motor <same as D15B which I have> Well question is, will I expletive anything up by using these spark plugs even though there like 3 threads longer then the ones I have now... We searched all through the computer at Discount Auto Parts to see what the plugs in my car now go in, but we couldnt even find them anywhere, I searched all different engines an everything an had no luck on finding my current plugs... I'm just kinda concerned that if there to long, they could expletive up my pistons or some ****.. If anyone on here uses NGK's an has a D15B or 1.6 vtec, would you mind letting me know the part number so I can compare just to make sure I'm not gonna expletive up some more ****, and create a bigger problem than I have already.... thanks in advance
