After lurking here for a year or so I finally did my plugs. I broke 5, 1,2,4,5,8. My 06 F150 had 100055.00 miles on it and was misfiring. I bought the lilse tool a year ago, so I was in good shape. Total time 5 hours. It was about half the time I thought it would take. I got a good deal on HT15 plugs off ebay, 1.75 a plug shipped. I realize some of you have had issues with the Autolites, I did too. Had cylinder 8 not fire after changing. Good thing I got two extra plugs, swapped it out and now it runs great. Thanks to all that have posted there experiences! I definately knew what to expect thanks to you!

Good for you! Now you can relax and enjoy the feeling of accomplishment.

 

Is the tool that good for getting them out?

thats alot to break

 

The lilse tool is worth twice what they charge for it. If I would have drove to my dads (400 mile round trip) and had his full snap on box , it would have been easier. I only had a hodge podge mix of miscellaneous tools. Chip

 

Did you do it cold? Or warm the engine first? I need to do mine also.

 

Remember how to change them.....the autolites won't be a good deal after 10-20k in miles....

 

Did it with engine warm
