Hi
Can anyone confirm the correct spark plugs for a 1978 911 sc (LHD Swiss Model). My original owners manual states it should be a Bosch W5D. Whats fitted at the moment is a W5DC. I have been offered a WR5DC+ as the W5D/W5DC is no longer available. Is this correct !
Any help gratefully received.
Thanks Phil
