torque specs on spark plugs? '05 V6

[rgcary]

Does anyone know the torque specs when replacing the spark plugs on a '05 4Runner v6?

I'm due to replace them.

Thank you.

I notice several here mention 13 ft.lbs. Just wondering where this spec comes from ? The Haynes manual says 15 and Denso says 18-21 for 14 mm plugs. That's 3 different specs
Haynes mentions anti-seize but Denso has no mention of it . Yes I'm getting ready to change mine

13 foot pounds and no anti seize- You will need a 18inch extension to make life easy. I did mine with a 12 but wished the whole time i had an 18inch.

13?

I just replaced mine and torqued to 15ftlbs with antiseize. ( also changed my plugs last summer using same torque spec with antiseize...no problems with removal or performance )

It is 15ft-lbs...........

I just finished my plug job , it was actually easier than I figured it would be .I was more irritated at catching my head on the bug screen when backing out of the engine compartment !!! They had a great deal on torque wrenches yesterday at the auto parts store , reg 39 bucks and sale was 14.99 , that was for a 3/8" 100-990 inch/lbs one.
I torqued mine all to 15 ft.lbs ( Haynes specs ) but elected not to use any anti-seize on the plugs after reading the NGK Bulletin . If your plugs are the coated type for use in aluminum heads they say not to use anti-seize because it messes with your torquing specs. In case someone is going to ask , here is that NGK bulletin.

from the factory repair manual :

the 1GR-FE is 13ftlb while the 2UZ-FE is 15ftlb.

Not to throw more mud into the waters here, but when you add an 18" extension to a torque wrench, keep in mind that the torque value applied to the plug is different from the setting on the wrench. In other words, if you're looking for accuracy, you need to compensate for extensions.

BTW, I don't use torque wrenches to install my own plugs.....just use my own experienced hands to snug them down properly.

Not throwing mud, but some light. I can't do the math, but the longer the extension, the "more torque" you apply..........would be interesting to see how much MORE one is actually applying. I'm sure it's negligible.

I just did mine today and torqued them to 18 ft lbs. Thats close enough for me. I didnt compensate for extensions.

It was probably one of the easiest plug changes I have ever done (v6).

 

[Uneek]

By "extension," what are we referring to?

If the extension is between the sparkplug socket and torque wrench, then no the actual torque value is not affected nor a need to compensate for the use of an extension for reach. This is most likely what's being discussed here.

If the extension is through the use of something like a crow's foot or a dog bone, then yes the actual torque value is affected.

When using a torque wrench with an extension, some of the torque is lost to the "flex" or "twist" of the extension. So if you were trying to tighten a fastener to 90 ft. lbs, for example, and you were using an 18" extension between the torque wrench and the socket, you would have to set the torque wrench higher than 90 ft. lbs. to compensate for the flex in the extension.

So you're not applying more torque with a long extension, you're actually applying less torque than indicated on the torque wrench. There is a simple formula to follow if you're doing precision work.

But at 15-18 ft. lbs. that amount should be pretty negligible. Thats barely snug, so I cant imagine there being much "flex" in the extension.
