Spark plugs.

[yaris1F8]

Hello guys they told me at the dealer to not touch the plugs before 192 000 kms.. is that possible ? What do you think ? :smile::cool:

[IllusionX]

160k km I think from the maintenance schedule. But I changed mines at 120k

[The Limo 2]

The maintenance schedule says 12 years or 192k km.

is that possible

Yes, with long life iridiums.
This is not your average nickel electrode $1.5 plug.

Ok thanks guys.. do you know the torque on the plugs.. how tight do they need to be ? :)

[jack black]

15 lbs/ft. Less if you use anti-seize.

I would remove (50k miles), inspect , check the gap and put back in with anti-seize on the threads for easy removal next time. That's 50,000 us miles. torque? is usually skill of the craft but if you want to be specific it's usually around 20-25 footpounds, and no the value does not change with anti-seize on the threads. 20 foot pounds of pressure is still 20 foot pounds of pressure no matter if the threads have a lubricant on them, it'll slide in a little farther with the lubricant on but not to make a difference, 20 pounds is still 20 pounds. if you had a soft alloy metal that would bend or something I would say yes torque them less if the threads had lubricant, I don't think in this case.

Sorry dude, you shouldn't be giving the bad advice like that. Oh, BTW, the head is made from aluminum, it's SOFT metal alright.

Note: If anti-seize compound is used, reduce torque by 30% to avoid over-torquing.

dude, you obviously have not take the spark plugs off either. the threaded part in the plug holes is not aluminum threads....dah. :tongue:

You're funny, but I'll bite. What is it then, titanium?

Most aluminum heads are just that, aluminum for the threaded part as well.
