You my friend are going to have all kinds of fun & beautiful scenery. Wish I were going with the both of you!!!!
Changed the spark plugs in my 2019 Chieftain to iridium. 10k miles and the original plugs show slight wear to the center electrode. Hopefully I won’t have to change them again until the 100k mark or beyond. The front plug (left side of the bottom picture) looks good with the heat mark showing at the halfway point of the ground strap and light brown color but the rear cylinder shows fuel additives not being completely burned off so it is covering the heat mark.
Iridium NGK plugs was the final piece I was missing in my Stage 2 upgrade, hard to describe the difference, just crazy how the plugs brought everything up a few notches and polished up the performance, all for $15, what a great improvement! =)
