Make sure you use genuine NGK plugs, otherwise you will have problems.
I got a new set put in some NGK’s.
Yeah, NGK's are great. Get the best you think you can afford.
I like NGK's iridium spark plugs personally
NGK FR6AHX-S 94279
NGK Laser iridium. Buy from a real distributor like Rock Auto.
I went with NGK plugs and coil packs at about 95k miles on my 2.5. I'm about 40k miles later and. It's still running great.
They are 2 hot for the engine , (the orange burns ) try colder plugs like heat range 8 NGK (SILZKR8E8G97080) are heat range 8 . The ones you have are 92422 are heat range 6 they are 2 hot . Same plugs fit my 2013 Veloster turbo fit your car .
I changed the plugs on my 2017 raptor recently with NGK iridium plugs. The punchline is that the truck started backfiring when I pushed it. I ended up putting Motorcraft plugs in and it cleared up.
It has 90k miles and we've been having issues with spark plugs. 3 months ago we replaced them after a cylinder 2 misfire. About a month ago same thing. Both times they looked terrible. Diode was all corroded and the threads had oil on them. Last night on my way to work cylinder 2 misfire came back. Anyway, I always use iridium ngk plugs as thats what's recommended but they are getting expensive having to buy them every month or 2.
