Buen video, gracias.
Good tutorial, but that smidge of engine oil on the plug threads is all but
vaporized and worthless right from the start. ALL engines need plugs
replaced with anti-seize compound on the threads. I just did my 00′ 4.0
today. Replaced another set using Autolite Platinum(single) tips. This
engine loves this plug as I had 10 years and 85,000 miles on them. A bit
too long to wait, but still starting, idling and running fine although a
few plugs gapped out at .075 and .077!
Thanks so much, you’ve filled me with confidence to perform this job.
