Spark plug wire #4: Chalky buildup on coil connection

Like the title says. I was cleaning up my engine bay and pulled the spark-plug wires from the coil pack to wipe them down. When I pulled #4, I noticed a chalky yellowish/whitish powdery build-up on the wire connection and inside the coil connection.

What up with that?

The other three wire connections were clean. I have a set of Magnecor KV85 8.5mm wires I installed about 3 years ago.

Thanks!

corrosion probably. get some dielectric grease on that bad boy. auto parts stores have it. just spooje it in there when you reassemble and it'll keep moisture out.
