Default Spark Plug Gap?

Rain today...going to chanve the plugs in my 2000 XK8 (not R).

Anyone know the correct gap?


2000 XK8 Convertable (90+K): Daily Driver winter and summer. Triple Black, 3-Gauge. Remote Top & RealGauge. Stainless hydraulic top lines, pressure reduction valve. Rebuilt throttle body and ABS controller.

2000 Corvette (110+K): Torch Red/Black/Black. 6 Speed. Rock solid and trouble free.

2003 Harley Davidson Deuce: Mid range cam, remapped EFI, pipes, dyno-tuned - waaay too loud for most.

JTIS says 1.0 - 1.1mm which equates to 0.039 to 0.043 inch for the 2000 MY. Specs changed to 0.051 for '01 and beyond. If you bought the NGK plugs ending in 11E they should be correctly gaped. If you bought the 13E that is factory gaped at 0.051 inch.

I just put NGK iridium in my 99 xk and the owners manuel stated plug gap at .050 and the NGK's came gapped @ .052. The NGK guys assured me the gap and the fact that they are iridium core everything will be fine. The car is running very good now. I also just replaced all 8 coil packs as well.

I just replaced the plugs in my 01 XKR with NKG Iridium IX #BKR6EIX. They are the best plugs I have used.
