Spark plug Champion or Denso

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.

Denso or NGk for anything and everything preferably dual ground spark plugs. I would get them rockauto as they have the best price and you can get the OEM brand.

Get the right dual electrode spark plugs, Denso or equivalent. They’re cheap, around $5 per plug.

Spark plugs are only $15 for Denso iridium plugs (providing the longest life) and they take no more than 20 minutes to replace them.

Spark plugs are simple too, just need the proper sockets and swivels. Took me about 45 minutes. That middle plug on passenger side is the toughest, but twisting boot 180 degrees and pulling it out from the front made it a breeze!

If you doing the spark plugs do the coils too. For the spark plugs use Denso 3499 (about 15 dollars each), for the coils use Denso 673-1310, (about 50 dollars each).

So i just ordered a pack of 4s (the left one is from Denso Japan) from a local distributor carrying Denso spark plugs and of the 4, 3 are made in China and 1 is made in Japan. Comparing them side by side, the China ones definitely look subpar to the naked eye.

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.

I quit buying Champions 40 years ago for shitty quality.
