Installed today , Notes i triple checked gap from Denso and it was 0.7mm for all 4 .
Gen 2 manufactures spec is 0.06 to 0.07mm
Conversion for help is 0.028in = 0.71999mm.So they where spot on (lucky)
These plugs are tappered so only 1/16 turn to tight once seated.
Original Fomoco plugs very clean ,but tight considering only 22500klms.
Very happy with result and group buy, i needed 1 step colder ,currently 225kw and stupid price here in AUS.
Thanks JMAC.
