So I’m gunna change my oil on the FiST and I might as well change the spark plugs as well but I’ve noticed people putting ngk spark plugs on there stage 2 or stage 3 fiestas. What I’m curious about is what’s recommended on a stock Fiesta ST. Is it worth upgrading to ngk plugs and what should I gap them when stock Or should I stay with standard spark plugs since I’m still stock? I haven’t been able to find any post about stock fiestas and plugs so any help will be great [emoji1305]
