4.0 spark plug gap
4.0 spark plug gap
Probably been hashed out plenty, but I don't have time to search right now. Hoping someone can post up before I get home. Manual says .061 - .068, seems like a big range of choices there. Thought about .065 just to split the difference, what do you all gap to?
even if you can't say anything nice or even help, go ahead and be rude. wow...stern words coming from someone who just joined last week...
JT...even the radiator core support says 61-68 thou. I shoot for 65 thou when I throw plugs in it.

No prob Chevy, just friendly ball smashing. Glad to see you've seen the light.
Can you guru's tell me what is the difference to expect from the low end to the high end? Sorry to keep kicking this horse, but I'm still learning this Ranger. I'm trying to keep her running her best.

um i think i rember it being .050 -.055 and just for the record a piece of paper is around .003
skyway is right..... With a coil pack you can open it to 0.65 otherwise if you're on a stock coil do 0.55
Edit: wait what? Why does my doc for my screamin deamon pack say open to 0.65? Should I open them to 0.75?
