Currently will be doing all fluids, filters and spark plugs so the car is properly serviced.
I got champion copper core for my 5.7 hemi which was what the factory had in it. I changed them at 68k and they probably could have gone another 68k they looked virtually new.Ran like a champ and I got them with rebates and at the end of the day they were 1.00 each.
I run Champion plugs in my Harleys. I have never had an issue with them and when I did try others, I never noticed any improvement over the Champions.
The proper champion plug is the "QL77JC4" gapped at .030".
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.
spark plugs and coils (first ride was smooth I though yeah but then manifested again) main motor mount (better revision, nothing changed, the vibration goes on)
But yeah, switch to another brand and stop using champions.
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
