Replaced plugs on 2010 Forester. White powder on boots.

Recommended Posts

2010 Forester. 30,456 miles. Non turbo.

Yesterday I replaced spark plugs. The old ones were original. The boots (especially cylinder #2) were covered with light colored powder. I am colorblind and cannot exactly tell what color it was: something between white, light grey or metallic. (I can hear somebody is chuckling).

Should I be worried or this is some kind of stuff installed at the factory, that prevents boots sticking?

It's just the stuff they use in the moulding process to keep the rubber from sticking to the moulds. Nothing worth worrying over.

 

I know how that goes, I have a close friend that's (partially) color blind.
