Replacement Parts Support
I ordered a set of spark plugs, and after about a week and a half called 1A auto bout them (the USPO tracking number would not work). Evidently they were lost int the mail and 1A Auto quickly rushed me another set (at no cost) which saved my bacon and got the F-150 running again. Thanks 1A Auto for your great customer support. After another two weeks the original order arrived which is now being returned.

Referenced the Wrong Plugs
Plugs were ordered based on the information provided. A call was made to verify that the correct plugs were ordered. We were told that youg on-line reference was incorrect and the plugs we ordered were for the 5.0 not the 4.6 V8. Plugs were graciously canceled before they were shipped. We purchased the correct plugs locally.

Do I need a special tool to remove the spark plugs?
Jeff P on Oct 10, 2016
BEST ANSWER: Yes there is an extraction tool. The metal sleeve around the eletctrode is pressed on and it tends to stay in the
head when you pull the plug out. This tool will tap threads into the sleeve then you thread another piece in to
pull the sleeve out. i have switch to champion 7989 plugs because they are a one piece plug and will not come apart
