If anyone has anything just shoot me a PM. What plug have you guys ran back in the day with the Ws7? It's a standard plug.
Part number RBD01143-WS7M will work for you and it looks like A-main has it in stock. This is the P/S/R set for the WS9 so it has 2 extra exhaust ports and probably the reason it cost more than the set for WS7.
