My son and I finally got around installing the ngk 2309 spark plugs purchased from
@Nick797 . The passenger side is easy while the driver side is what you’ll waste the most time on. Luckily my son was able to crawl under and take care of the driver side.
In the process I discovered I have a valve gasket leak on the passenger side.
About 4 or 5 spark plugs were wet with oil on the threads. I’ll be taking the truck in for warranty work.
On a positive note the truck does idle much smoother.
