Spark plug torque spec?

[Fletch124]

Does anyone know the spark plug torque spec? I cant seem to find it in the TSRM.

Thanks,
Reid

I think its either 14 or 16lbs.

I think it is 12 or 13.. Somewhere in the 12 -14 range will be fine.

huh?? you guys actually tq to spec... never in my life have I done that. always the rule of thumb method you know. never fails.

With spark plugs yeah. Anything on the head of this car, you beter tq correctly except the head bolts/studs. Always 75+ with those, factory, or the preferred ARPs.

Actually, if I remember right the torque spec on the spark plugs is about 23 lb/ft. I am a mechanic by profession. Neither me nor anyone else uses torque specs unless it regards engine internals or manifolds. Everything is as stated earlier "rule of thumb". Basically, experience.

 

[Mk3runner]

100% agree with that.

By noone else, I mean in any shop I have worked in. By the way, looked up the torque spec on those spark plugs. It is 13 lb/ft.

Use some Nickel Anti-Seize also so they don't get stuck.

ABSOLUTELY!!! I should have mentioned that.

So what is the torque spec?

edit: Okay, TSRM says 13 ft/lbs.

LOL I agree....sounds like newbs to me, but whatever gets you going. to each his own.:biglaugh:

I'd rather listen to an NGK engineer than you douchebags.

Get a fucking grip! whos a douchebag ass... you dont need to use a torque wrench to tighten spark plugs. If you feel you need to by all means go ahead. You are out of order.:nono:

Good Numbers to know, Thanks Matt

Douchebags? I beleive you are referring to those who have mentioned you do not have to tighten spark plugs to a precise manufacturer's torque specification. Torque specifications are there for a reason however are inherently inaccurate. Actual clamping force of a fastener is not measured in torque. On top of that, the best mechanics I know in the business as I said do not torque bolts to spec unless it is more critical such as engine internals. If you want more, I just left a job where I worked with a mechanic that did assembly work for Lull at his previous job. Even on the assembly line on "critical" bolts are torqued to spec.

I'm from Alabama so it's always "hand tight + 1/4 turn".

75 ftlbs

i did 97 ftlbs

wanted to make sure they weren't gonna fly out upon compression

Good lord . . . relax people. I can't believe people get slammed for trying to do a job right. All it takes is for you to experience one stripped spark plug hole (or any fastener for that matter) and you'd torque the plugs when installing. Personally, If I have torque specs for any given fastener I'm working on, I'll pull out my torque wrench and do the job right (like its so difficult to do and time consuming - can you feel the sarcasm??). Nothing like being torqued with a 'Dead on balls accurate' Snap On torque wrench ... 'Click' Ahhhh!
