NGK(6509) LTR6IX-11 Iridium IX Spark Plug, Pack of 1

Q: Has anyone had these for a while and did you have any problems since installing them? I have a GM 3.6 with COP and want to replace stock plugs.

I've had these for 2 years and I havnt had any problems after installing. Noticed a difference in performance and fuel economy

Q: how do they work on a mustang 2012 v6 ?

Thank you for inquiry. Yes, this will work on 2012 Ford Mustang V6. Don't hesitate to contact us if we may further assist you.

Q: What size socket wrench does this fit? When measured, it fell between 9/16" and 10/16"

There is no such thing as a 10/16" socket. I0/16" is 5/8". I use a 5/8" spark plug socket which has a rubber insert so the plug stays in the socket when taking out and installing. Saves a lot of trouble. Socket wrench is what you install the socket or extensions on which you will need.

Q: Suggested torque for these in an aluminum cylinder head?

According to NGK, it depends on the plug's diameter: 18 mm 35 to 40N·m (3.5 to 4.0 kgm) 14 mm 25 to 30N·m (2.5 to 3.0 kgm) 12 mm 15 to 20N·m (1.5 to 2.0 kgm) 10 mm 10 to 12N·m (1.0 to 1.2 kgm) 8 mm 8 to 10N·m (0.8 to 1.0 kgm)
