i THINK all the modulars take the same plug. AP103's!! or APP103's .......

on the V10 the motorcraft equivalent is a platinum 103. it's kind of a toss up between a platinum and DOUBLE platinum. i used the plat 103, torqued them down and checked them after a tank of gas.

check your local wally world and it will save you a few buck compared to the motorcraft. and on a side not MC and Autolite are the same company........different wraper. so if somone says autolites are junk and they only run MC..........just smile and agree, hahaha!!
