What would be good for my spark gap on my car, 054 or .053?

Hi,

If you are replacing the plugs, either of what you indicated is fine. The manufacturer gives a range for setting the gap. In this case, it is .052 - .056.

I attached a pic below from my manual. Let me know if this helps or if you have other questions.

Take care,

Joe

Hi,

I wanted to add a quick video showing how this is done. I'm not sure if it is needed but I thought I would add it in case.
