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.

Music So.. I didn't get to change the plugs or do anything else to my car yet as I pulled something in my back Saturday morning by just coughing. :(

Do I need to use Dielectric grease as well?

Not sure if I am getting confused with my 2002 Toyota Tacoma that I also plan on changing the plugs, wires (including Ignition Coil on Plug Boots). I don't remember ever having the plugs changed...

I am a complete noob when it actually comes to doing anything mechanical on the car (I know.. it's obvious ;) )

I have yet to find a repair manual for the 2008 Focus... guess I might be able to refer to the one I have from my wife's old 2003 Focus for some things?

I was hoping would have more info around these things, but not so much.

Music Sounds good. Thank you!

sailor Not needed.

The tapered seat design on these bottoms rather suddenly & firmly if you're used to the type with separate gaskets. "Snug" or "Firm" is "Gut enough", I only use a 6" ratchet handle for installing plugs 'cause you don't want to "reef" them in there.

They'll be hard enough to break loose when you change them next, no reason to overdo it.

Music I will be replacing my spark plugs with the Autolite A103s, what is a good torque wrench for plugs? Or is it really not needed?

I did a few searches and didn't find anything.

a car nut VW used the silver Bosch plugs for several years during the 1980's as a OEM plug, as I remember they did idle better than the regular Beru or Bosch plugs at the time but were rather expensive. I installed many sets of these until VW changed the recommended plug from silver to copper later on.....
