Will this sparkplug work ??????

[MAT2CH]

I just got my 03 L back from the dealer and one of the things they did was change the sparkplugs. I noticed the plugs they put in were AGSF 12F M1F4. Are these plugs made for the Lightning? Will they work on a basically stock engine? The guy I asked at another Ford parts counter said they should have used the one recommended for the Lightening.
Anyone have any comments?
Thanks, MAT2CH====================

The ones that the SVT certified stealership put in my L are:
Motorcraft AGSF 12FM1 PLATINUM.

I am now running NGK TR6 plugs because of the 5lb pulley that I installed.

screw the stockers and put a set of TR6's in it.

Ditto. :thumbsup:

Hell yes.. Put in some TR6s.. I had my lower pulley tuned on stock plugs, and had the TR6s put in, and i couldnt believe the difference in the way she ran. It was running smoother, and stronger. VERY worth the money.

If anyone didn't know you can get TR6's at Napa for $16 and some change.

 

[nastynivek]

.036 also. And yes, the NGKs are dirt cheap. Definitely won't hurt the budget.
