Confirm spark plug torque? (3 Viewers)

[Super77]

13 ft-lb is the value I’m getting from multiple sources. Confirm? Seems light.

PO had the right iridium plugs (NGK IFR6A11) installed but I swear the mechanic used an impact gun to spin them on. 50-60 ft-lb to crack, my guess. I just had a puckering half hour trying to get them out. They stuck and chattered all the way out, but I don’t see a sign of thread damage. I’m using a light coat of copper anti-size and torquing them to spec.

Mine came out tough too.
From what I have read - absolutely NO ANTI-SEIZE, that's ironically what makes them hard to get out, acts like threadlock.
I went past torque spec due to the plug's propensity to back out on their own (which is what turns the anti-seize bad)
although I wasn't using a torque wrench so I couldn't tell you exactly where I ended up.

Read in the "ticking time bomb PSA" thread about the anti-seize and more torque advice.
