i have an 08 5.4 3v will i have the spark plug promblem i have noticed some say on motors built before 08 well if its an 08 it was probably built it 07 any help

 

Its in the sticky at the top but I can let you know the date of the motor build is on the driver side valve cover sticker. Anything before 10-09-07 has the two-piece plugs with the breakage issue. Anything after that has a different head with the one piece plug. Luckily mine was built in Jan of 08. You should also notice a different coil boot. Forgot for sure, but i believe the ones with the one piece plugs should be brown and the ones with the bad plug issue are black.

 

Thanks man

 

My head has 10-30-07 printed on it!! Hope that's far enough down the line for the new heads/plugs lol
