Versachem® Anti seize for oxygen sensor..

[Jarpin]

This is just a question of type...and ease of removal after 8+ years in high heat application.

I have both a Grey looking paste and a Copper colored paste. Which is best?

Thanks.

Bosch and NTK oxygen sensors come with factory-applied gray/silver anti-seize.

Denso oxygen sensors come with a packet of copper anti-seize you have to apply yourself.

So both colors are used. Not sure it matters.

If only doing a couple of O2 sensors and a few bolts get a small tube of nickel anti seize.
