Re: Spark Plug Heat Range
Well I installed the BKR7E and right from the key on and idle I could tell something was different. Gapped at .050". Idle was way smoother. I have a Fidanza in the car, and the "box of rocks" was not to be heard or barely. I have pulled one plug to check heat range, and it actually looks as if I could go one step colder. Any thoughts on that? One of the gurus on 3rd Gen would say just give the motor what it wants.

Re: Spark Plug Heat Range
Been running the same plugs (BKR7EIX) for about 6 months now, very happy with them.

Re: Spark Plug Heat Range
Should have asked this earlier, but what gap? Of course, yours are the Iridiums so that could make a diff.

Re: Spark Plug Heat Range
FR,
I have pulled the plugs after doing a scan that included WOT run and driving around to read various points on the VE table. Looking to read ground strap, which now shows a line much closer to arc of ground strap. I'm running .050" gap. Any comments on that? |
Re: Spark Plug Heat Range
were you looking at the plugs after a WOT/clean shut off run? i'm not sure what your looking for in heat in the ground strap but it sound about perfect right now for me. i'd go away from the .050" stuff myself. if you want to pursue the larger gaps your better off to clip the ground strap back & side gap. NGK iridium plugs actually come with the groung strap cut back a tiny bit.

Re: Spark Plug Heat Range
would .40 be better ? any thoughts on the E-3 plugs that are out now?
