So my frined just got a 20v (woot) and he brings it over today to check some things out. pull the plugs and they are denso iridiums. DENSO. in a 3B? i say no way and just run the F5DP0R, but was just curious as to what kind of plugs everyone else has run in these and the results. I know my dad runs the oem or there is one other plug that has been sorta successful and that is some hard to find ngk 3-electrode plug (forgot the pn).
