Elaborate on what, bud?
Denso IKH22 plugs work perfectly, in all conditions and at all power levels.
0.8mm gap as required, 0.4mm electrode and V grooved tip provide a superior spark to the NGK plugs.
But you already knew this.
You can find the IKH22's on eBay Motors and get them sent over for less than I can get them through Denso in Croydon.
