I have heard a few good things about them.
Would you suggest PFR7B for a MY98 WRX STi (JAP) ?
Good price too, where did ya get them ?
What gap would you suggest to use....

I have seen it posted elsewhere that the HKS version of the iridium is a better spec than the Denso version - but this could be sales talk as the HKS is more expensive.
I have used both the HKS Iridium, which I used to get very cheap - under £50 for the set - but when that supply ran out I moved to PFR7Bs. These are gapped at 0.6mm - which is a bit tight - but running boost up to 1.7bar.
The Iridiums could be run with a much wider gap - 0.8mm at least and were very good. Subjectively I preferred the Iridiums - but I have no objective data to back it up - they are both good plugs.
For the really wild cars there is the extremely expensive PFR8bs! Not for everyday use methinks

PS Car is an Sti V - and I have used the Iridiums on the car in both standard and modified form. The NGK only when it was modified.
