Whats the easiest way to replace spark plugs on a 2006 F-150 4.2 Liter V6?

 

by using a ratchet to unscrew them and then replacing them just kidding.

I've got a 2000 4.2 and didn't really have any trouble replacing mine. It's a good idea to replace them one at a time so you don't mess the wires up. When you go to thread the new plug in I like to insert the plug into the cylinder and hand tighten it to make sure you don't cross thread it - once it's snug by hand snug it up with the ratchet.

Most of the guys on this forum agree that you should only use motorcraft plugs as these trucks don't like aftermarket plugs.

 

You say just kidding but that is the best answer for that question.

 

haha yeah I know I just don't want to needless **** anybody off for whatever reason!

 

write a check to yor mechanic!

hey you said easy, not painless or cheapest!
