DF140 spark plugs

[Kari Vainola]

does anybody have experience using iridium spark plugs instead regular NGK BKR6E or EK(copper?) spark plugs? Fuel consumption/ throttle response/idle rpm etc? Which one is the best choice for trolling speed?

[boats.net]

Suzuki only list the BKR6E plugs and no other options.

NGK catalogs knows only iridium sparkplugs? I will still use the regular plugs

If you want to try the iridium plugs, NGK lists the BKR6EIX for the DF140. Gap at .032"
