At around 120,000 KM plan for spark plugs. It's easy, especially if you get a 1/4" torque wrench and 14mm 1/4 deep well socket.
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.
I bought a 19’ Premium at 17 it’s a great little car beat the shit out of it for 4 years straight and it runs amazing still. Handles well in the winter as long as you have clearance it’ll get you there in one piece. Regular maintenance along with trans fluid change, spark plugs, brakes, diff fluid change. I’d recommend a cpo premium . Great value.
In a pinch I use champions.
Champion are the only plugs I’ve had the ceramic crack on, so no more Champion for me.
My service center guys installed Champion plug instead of Bosch on my turbocharged Altroz. Company user manual clearly says to use Bosch in TC. My car's economy has dropped significantly...and I'm just frustrated.
I won't run champion plugs in anything but lawn mowers. That's the only thing I've put them in that didn't get angry about it. Guess everybody's vehicles are different, but personally I don't think they're very good plugs.
Champion spark plugs are rubbish, not sure why they’re even sold.
