These are the spark plugs Manic recommends when you get their tune NGK 1422 ILKR8E6. When I checked the gap on all of mine when installing they were .022"
The last character in the NGK part number is the pre-set gap size, 0.6mm, or 0.024". Your tuner might recommend a different gap, depending on your mods, but 0.6mm is working fine for me.

+1 the 0.022" gap. It helps ease the load on the coil at high boost. In addition the shorter insulator helps prevent preignition by keeping the tip cooler. With the smaller gap comes hotter spark so change them out at 30k miles for best performance as the hotter spark will erode the tip quicker.
