My ‘15 Mazda 6 has 76,000+ miles, I haven’t done any major work on it. The spark plugs + ignition coils haven’t been replaced. So I changed them at the same time?

Owner's manual says change spark plugs every 75,000 miles. Should I just do it earlier?

I have been getting racked over the coals paying for sparkplugs and ignition coils on this damn 2014 mazda 6. I'm about to learn how to do this stuff myself. I had to replace spark plugs twice, and replace each coil, only 138,000 miles on it.

Saylur Rodriguez says:

When you tighten the new spark plugs back on do you want them snug or as tight as possible?

Jose Gutierrez says:

Thank you so much for this guide, you have saved me $299 the dealership wanted to charge me.
