Discoloration on Spark Plug Lead

[avrojockey]

Has been this way since I installed these ACS leads. Not sure what that’s from. Only on one lead, ground and inflight mag checks ok, not discolored under adel clamp.

What day yea?

Its just some of the chems in the adel clamp rubber leaching out into the spark plug lead silicon rubber. Nothing to worry about. It happens sometimes. Sometimes happens on powder coated engine mount too. No big deal.

Yours has probably gone about as far as it will go. Shouldn’t get much darker.
