Spark Plug thermal heat paste

I've been using this..1oz will last a long time and the price was right. http://www.mcmelectronics.com/product/20-300

Hi Roger,

I know this thread is like ancient, but I have a tube of Molykote 44 - are you saying it can be used on the spark plugs as heat grease?

NO!

MolyKote 44 is a High-Temperature Lubricant.
The spark plugs need a HEAT-SINK Compound.
It is not applied for lubrication, it is used for Cooling.  Lubrication is a side effect.
Common formulations consist of Titanium DiOxide powder with a Silicon Grease Binder.
It is commonly used to thermally bond computer Heat Sinks to the CPU Chips

If there is anything more messy than Anti-Sieze Compound, this might be it.  ?
