So I was going over my fusion with a careful eye this week when it occured to me.. 68,000 miles.. Maybe I should pull a plug and see how things are looking. Upon doing so I noticed the tips were worn and the plug overall needed replaced... So, having an auto repair garage, I got on my commercial account and pulled up my car to look at the options.. We all LOVE pictures right.. So I'm looking @ everything from Autolite XP's to Motorcraft OE...
Now the exciting part.. I did the research and decided yea, lets go oe because I haven't done anything performance so what will I really see in spending 7+ a plug for the autolite's.. Well according to autozone and napa.. My motorcraft plug SHOULD BE an SP433... Which factory number is AGSF 32WM... WHAT I ACTUALLY HAD was AGSF 32N... Interesting I thought so before I accepted what I was being told to be OE I decided to try FoMoCo.... Yet again.. same story....
Talked to a tech @ a bar thursday night who said he recalled the ford 500 3.0L running an SP413, AGSF 32N.. Now we're getting somewhere... This plug is Nickle grade and not rated past 50,000 miles.... He went on to explain the new factory spec is this SP433 which is 100,000 mi RATED plug..
To sum the whole story up.. IF you own an 06,07,08 with a 3.0L You possibly have the inferior nickle plug and you should probably invest in a tuneup and the SP433 plugs.. It cleared up my early morning roughish idle and my light hesitation.. IMMEDIATELY!
Thanks for reading I truly hope this helps someone down the road
