notfortheweak Just put the autolite 103s in. Better idle, more pep. Iridiums were put in 5 k miles ago. Car hated them.

puffingonj Any turbo guys had the autolite a103s plugs separate?? I can take the porcelain and spin it in the steel. Replaced with new set 3 days later same thing. Since then I put the ar103s and I have yet to pull a plug and check them. Just wondering

sailor Correct, this is the Duratec Performance '08-'11 section for MkII owners.

Try the MkIII sections, your engine type is Duratec TiVCT.

Welcome to FF, you should find a lot of info. once you get into the MkIII sections & general areas that fit all models.

macguitarman Guys, this thread is a bit old, I have a 2013 Focus SE, Autolite A103 apparently do not fit on this year.

Stock plugs are Motorcraft SP-535

what is the deal with these Foci and this dead spot lag when at full stop and gassing it, i hate it, it sucks.

ellmarshptbo well I changed my spark plugs today in my new to me 06' Focus. I used Autolite 104 coppers. I did not know the mileage of the plugs, but the previous owner had put Bosch platinum's in her! they didnt look too bad, electrode was worn. I guess on the bright side they were not factory at 200XXX KM's ;) I was greeted with better start up, better accel espcially in 1st gear and a smoother idle. Thanks everyone!

PSUrivie When you change your plugs, use either anti-seize or go old skool and use a dab of oil on the threads of the plugs to they don't corrode in the head.

Miztaken1312 I'm really late to this, but Music if you're looking for an 08-11 shop manual, I uploaded mine and was giving it out to members.

You can buy this at pretty much any automotive store, also the internet.
Thanks! Didn't realize Haynes had an online version as well.
