Going to change my plugs 04 5.4 3v. Will it help if i put some liquid wrench down on the plugs and let it soak some or do i need to us something else.Any help would be great. Thanks RoushRich

 

Goodness man, you need to read the TSB and follow it carefully. You need Ford carburator cleaner, not Liquid Wrench. Do an Advanced Search for the sparkplug TSB and do some reading. If you don't follow the TSB, you are at high risk of breaking them off. You should have one of the tools for removal handy too, just in case you break one. The Lisle or the homemade.

 

Find and follow the TBS to a T
