I'm getting ready to change the plugs and I know for the aircooled Porsches anti-seize was not recommended on the threads. Should I use or not on the 996TT?

 

it is not nessesary to use a anti seize paste

 

Anti-seize should never be used on threads for the plug. It is better to just put a light coat of motor oil on the thread and that is all you need. If the anti-seize just so happens to get on the tip of the plug, you will then have problems.

Also, it is easier to to unplug each of the oils before you take them out of the hole. If you leave them connected and try to maneuver them around to get them out of the way, you can easily stress the out and could result in breakage. If you press on the rubber part, you will then feel the clip that holds it down and it will easily release the coil pack.

 

Good info - thanks!

 

Being a contrarian I put anti-seize on spark plugs and have for years. I understand fully the negatives regarding getting it near the electrodes and into the combustion chamber. A very light coat will make for easy removal and help protect threads in the head against galling, cross threading and other damage. I got into the habit working on motorcycles for a living, most with aluminum heads and experiencing spark plug seizure numerous times and removing aluminum head material along with the spark plugs on occasion. I feel protection of the threads is more important than risking anti-seize in the motor.

 

I put anti-seize on the plugs both times I've changed them.

VERY thin, and keep it away from the sealing ring- I put a thin 'swipe' around the threads towards the electrode end, then use a clean shop towel to wipe it around and almost off- just a thin code in the threads. Keep it off the electrode itself and off the insulator as well.

This was confirmed by Kevin at UMW,

 

Yes if you're careful with the stuff.

I do exactly the same and always have.

 

Add me this list... regarding the usage

 

Fully agree with this as well, just be careful when you do it.
