I was going to change out my spark plugs this weekend and heard something strange. Do the f-150's now require you to soak your spark plugs. This was news to me and sounded funny. If anyone has heard this please let me know. Thanks guys!

 

5.7? hm thats strange. you mean 5.4? anyway, yea search and you will find your answer on this forum

 

Yeah Sorry accidentally hit 5.7. Do you know what to soak them in?

 

You need to do a lot of reading before tackling the job. Pull down the search tab, go to "advanced search" and type in "sparkplug TSB", or changing plugs in 5.43v.
