Has anyone tried these plugs the tech at NGK said they would be good for high compression and not go quite as far into the combustion chamber because it doesn't have a projected tip like the NGK 2315 and with a factory gap of .044 they would be better for closing the gap than with a plug that comes set at .052 They are the same heat range as the NGK 2315 Thanks
I got a set comming, it sounded good to me and they do come in 1 more step colder than that to I believe I think it is a #7 ( LTR7IX-11)
They came but the end that goes into the head is right but the opposite end is shorter than the NGK 2315 will the coil still cover it. Think they will still work OK ?
