I'm nearing 100K on my 2011 F250 6.2 and I was planning to change the plugs pretty soon. I was just wondering if anyone has done this themselves on this motor. If so, any tips, things to look out for, etc.? I realize there are 16. I've always changed them with no problem on my 2v 5.4 super duty.

 

Subscribing. Also what plugs would the masses recommend?

 

Not a lot available aftermarket for the plugs. If you want stock get the Motorcraft SP526(Double platnium tip). If you want a better performing plug I would use Denso ITV20's (Iridium fine wire) and change them every 50K at least.


As for R&R of the plugs, pretty straight forward. Plug gap is 0.042-0.046 in and plugs should be torqued to 18lb-ft.

 

Has anyone got a procedure for this? Looking at doing a spark plug change on my 2011 f350. looking for any tips and tricks. Truck has 93,000 km so figure it's time. Local dealer wants $650.00 parts and labour so am going to tackle this myself.

Thanks for any input
Stew

Larry,
Thanks for the 6.2 info

 

Thanks for the procedure.

 

What is hot soaked or cold soaked??

thanks,,,

 

Anyone have spark plug brand and part numbers recommendations??? Never mind I see I posted this very Q back in Feb.

 

I would highly recommend sticking with Motorcraft.

 

Means fully warmed (still hot after driving) or fully cooled(sat for an hour after driving).


You want to change the plugs when the heads are slightly warm to the touch but not so much as to be uncomfortable.

 

Thank you Gangly.

 

Cold soaked would also mean overnight or for any extended period of time beyond a few hours after vehicle was last operated....I would warm the truck up for 4-5 minutes and then let cool some before removing the plugs.

 

How about a dab of anti-seize on each plug before installation; or at min a dab of 30w oil. I typically practice one or the other depending on the engine. Is this recommend with the 6.2???
