I bought some spark plugs for my wife's 2002 Windstar. I couldn't put the back three in. Took them to a place to install and they wouldn't use mine (big disapointment here), had to buy from them! Now I'm stuck with these spark plugs. My question is, would these work in my 1996 Taurus? Let me pose this also... The OEM plugs for the Taurus is AGSF32FM and these plugs for the Windstar is AGSF42FM, just the difference of the 32 and 42. Could they be interchangeable???
Thanks Joe :blink: :blink:

The numbers refenece the heat range.

No, they will not work. The 42's are too hot for the taurus. The Taurus combustion chamber runs too hot to begin with - the last thing you want to do is use a hotter plug.

EDIT: if you ever want to go to a colder plug, you CAN use the AGSF22FM's.
