Spark Plug question

RE: Spark Plug question
just buy some NGK BKR7E for $10 and gap them to .032 and when you get your chip just bring them down to .028. These are very nice plugs and you can get a set at you autoparts store for the cost ofone Iridium IK22. And even if you change them 15-20k miles thats still 60-80k for the same $40+ spent for some iridium plugs.

what do all you use to gap them? i use one of those 50 cent gappers looks like a silver dollar. i dont think its accurate at all.. i might try my brothers wire type gapper he says its much more accurate

No it won't hurt them. They just can't take a lot of bending pressure or they will break the end off. I've always done mine with that style of gauge. The wire type gauges are fine for copper plugs that have a heftier electrode.

RE: Spark Plug question
Is anyone running the copper NGK's in their's? I didn't think anything about them when I was doing mine a month ago but my brother with an S4 used them and said that they are just as good; especially for the price. We would have to replace them 4 times before the cost would equal that of the others.
