Last time I still had the original O-ring and found a perfect match. or so I thought. crack.
Darn things only about a toothpick size O-ring 4 1/4" diameter or so.
The real kicker is that I bought the car new and have no valid reason for ever removing the
cap (less plug wires) because it appears to be a lifetime part. A aftermarket cap was history in 10,000 miles.
Oh well :/
