Spark plug Champion or AC DELCO

I just got a new to me 2016 f150 with 120k. Did air filter, cabin filter, spark plugs (had a misfire) and boots and oil change. I used champion plugs but most reccomend OEM. Got a wix air filter and a fram oil filter. I used full synthetic 5W-20 Valvoline R&P oil. Use rock auto for parts if possible.

Stick with Champion plugs in the 4.0L inline 6. Anything else will have you chasing a “stumbling” idle.

I use champion on my 04. No issues. The more expensive ones that’s when the issues start

I use Champion in my 02. Never had any issues.

I’ve been running champion plugs for about 40k mi without issue.

I recommend nothing with platinum. I've had problems with those in my 1980 gbody with a 305. I just keep it simple with old ac/delcos now. Keep it simple for less problems.

So Champion sucks, more like Chumpian.

Some of my best vehicle purchases have been trucks with "misfires" or "engine issues" and almost all of those have had goddamn champion plugs in them, or a champion distributor.

But let this be a lesson never use champion plugs again

Champion are the only plugs I’ve had the ceramic crack on, so no more Champion for me.
