Hey all, Was chatting with a buddy today and he asked if I ever gapped my spark plugs. He recommended puling them and checking the gap as his were all over the place when he first got the car. He also recommended one step colder plugs (NGK) So heres what I've got. 2016 with 3.5k miles. Mods are roush intake, cobb rmm, stage 1 OTS tune, and stage 3 damond OCC. Are colder plugs only needed when going BT, or should I invest now. keep in mind, winters here are cold (10degrees in mornings normally) and I know the step colder plugs suck in colder weather on startup. Also is there a need to pull stock plugs and check the gaps from the factory after >5K miles if I do not need new plugs? Just wanted to get more thoughts on it. I'm planning on going stage 3 here in the next 6 months. Thanks!
