Can get it at Maplin, or ebay. I used thermal compound used for mounting heatsinks to processors on pc motherboards. Not quite the same, because it has real silver particles in, so is actually a conductor. Put it on each pin individually (make sure just on each pin, so it doesn't short!), the push the plug back on a couple of times. My stuff was called "Arctic Silver", its about £6 for 30ml. You'll only use a tiiiiny bit, but you could do every plug in the bay, would be nothing but benificial! I did have a look for mine, but it got binned when I moved out Failing that, maybe its time for tfsi coils?!
