What did you do to your 2019 and up Ranger today?

I don't like how dark those plugs are. Odd that #1 and #2 were the hard ones to pull out. Usually, it's be back two, especially if you have a cowl leak onto the spark plugs, like some have had with the 2019-2023 models. Hopefully, things will be better with the next change and it is purely how the previous owner drove the truck.

Mine didn't look too bad at 100,000 miles when I changed mine.

There was a fare amount of dirt and debris under foam cover. There were leaves that are not native to TN under the cover. I think some of the difficult was debris in the spark plug sleeves.

I've heard mixed opinions on engine covers in general. Some say to remove them because they trap heat and debris. Some like them, because of the cowl leak I mentioned, because they help keep water from dripping and pooling in the spark plug tubes, causing corrosion problems. I have mixed feelings on them myself. I like the look they give most engines and they are nice to have if you do develop a cowl leak. But they do trap debris and I can see the argument about heat being trapped, cooking the stuff under the cover.

That actually looks much better.

Best thing to do when you see that is a pistol grip air nozzle. Blow them out before you take anything apart. Don't wanna get that stuff in the engine. I have used brake cleaner before. Then hit with PB Blaster (My spray lube of choice. Use whatever ya want.) before you pull them.

Too late, they have already been changed out. But I did blow out the sleeves before I pulled the plugs.
