Re: Spark Plug Gap Discrepancy
I picked up a set of the Denso Iridiums this afternoon. They were indeed all pre-gapped -- just to the wrong distance! Every plug was set to 0.041-0.042", so I did have to fix them to the 0.031 they should be for this application.
They still would have worked at 0.041, but I'm a purist and want everything perfect. So, that means to the thousandth of an inch for me.
