Iridium spark plugs - adjust or not?
Finally got myself some grade 8 iridium sparkplug to sort out my occasional lift-off det.
I would have set them to 0.65mm, as I believe this is a good gap for my MY94 WRX which boosts to 17psi, but the plugs came with a warning not to change the gap size as it may damage the iridium.
Shall I do it of not?
