Spark plugs install - how do you do it?
 

I have the engine out for my transmission rebuild and refreshing the ignition. How do you all install your plugs?

Dry or anti-seize?
Torque or by feel?
What torque if you use a wrench (30 Nm per factory manual)

Thanks!

Since engine is out definitely torque them all
Itas almost impossible to get accurate torque on some of them while engine is in..especially top 6
I use anti seize...some dont, Its probably a 50/50 on that

Anti-seize, and I torque by feel (the anti-seize saves me there!)

Anti seize and torque with a torque wrench. If you're asking on here, your elbow is not calibrated enough.

Great input. Thank you. I did 3 today and put the new ones with 28 Nm per Bosch spark plug box instructions. I have a well calibrated elbow, but if I can like to use the torque wrench!

You will read a lot more questions on here soon, please visit and help as you can!

Thanks!

The torque values stated by the factory are without anti-seize if my memory serves me right.

Cheers, James

James,

I did them dry. Not planning on leaving these in for 100k miles.

Torque specifications are for new, clean and dry threads. Add rust, corrosion, oil, anti-seize or a combination of them all and the specs quickly become guidelines. Makes the old elbow and the chrome eyeball pretty accurate!!

Anti-seize, always.

Anti-seize and 18 lbf.ft. for torque.

The recommended torque for a 14mm spark plug with washer in an aluminium head is 18 to 21.6 lbf.ft. I chose to go with the minimum value since I used an anti-seize compound on the threads. Spark plug torque specs are for dry threads.

As for the anti-seize, I use a high temperature copper compound. There are various types available. The one I now use has a far higher temperature rating.
