Do they have any type of oil in them? The reason I ask is that when I changed the plugs the last time the plug that is closer to the driver side had a little oil around the top side of the plug. But the oil was really clean. So that is why I am asking.

Also how do you clean the points that go on top of each plug?

Thanks

Shouldn't be any oil in it, ultimately it's just a set of coils of wire for each spark plug and some electronic circuitry to control it all.

There is oil in it, used to help soak heat away from the coils. One of the modes of failure is the oil leaking out and something overheating.

+1 on their being oil. If you see oil you will likely have a failure soon.
