Coilpack insulation/paint

Splinter · Post by **Splinter** » Fri Jan 13, 2006 2:20 am

Just received my Diamond coilpack from Blackbart, and the paint on the iron plates is started to flake off. Should I repaint this before I install it, or does it not matter?

mine is like that, don't think it matters

If I want to paint it, so it looks pretty (:lol:) can I use this semi-gloss krylon I already have, or does it require high-heat paint?

We've got a can of matte-black paint used for woodstove furnaces in the garage.

iirc it bolts to the intake?? not sure but my rule of thumb is anything near the engine gets high temp paint

What does the coilpack ground through

The only reason you should paint it is to keep it from rusting. Electrical insulation of the ferrite is unnecessary.

The primaries of the coil are grounded through the ignitor when the ECU thinks they should be.

The secondaries of the coil pack don't ground through anything -- the spark travels out one coil tower, through the plug wire, across the plug's gap into ground, through the engine block to the other plug, across the other plug's gap into the plug wire, through that other plug wire, and into the other coil tower.

Oh, and it should never get much hotter than 200 degrees, so you can get away with a good non-high-temp paint, but high-temp paint would probably last longer.

Duh of course.

I need to start thinking about this stuff instead of running to the board for every question
