Thanks RBarrios. Yeah, cylinder 1 is directly above the PVC on the 2.4L and to the left are the VVT solenoids.On the 3.6, i believe the number 6 is always the dirtiest.... if im not mistaken, its the plug closest to the pcv valve on the valve cover... the pcv tends to clog up the little breather holes....
Is there a pcv near your dirtiest plug?
Not a problem, looking at them harder I think I can tell a difference.@Ebeo1 , your plugs are the same as mine that some are more dirty comparing to others. Thanks for sharing.
How many miles were on those?.My opinion I don't think there is much carbon build up. I did a spark plug change in 2020 and took a picture.

My cam shaft positioner went bad about that time. My car would stumble on acceleration and stall at red lights. That's when I got proactive and changed the plugs at the same time as the positioner.Since the factory recommended interval is 97,500mi. they really don't look that bad.
Yes I have used a fuel additive a few times and that has helped.Have you had any of the oil consumption issues with the 2.4L?.
