spark plugs

Postby JimCrawford » Fri Oct 01, 2021 9:44 am

Good Morning, tapping into the font of all knowledge again :)

My engine is a Rollason Ardem, originally 1500 but now 1834, ignition is twin Leburg. The data I have is rather old and calls out Champion L T or Lodge H N plugs. these are old designations and when I look up the current alternatives they appear to be Champion L82C or Bosch W7AC. However all the VW specialist sites I've visited list the Bosch W8AC as the standard plug for the Type 1 engine, the difference being one step in heat rating.

What is the recommended plug? (not necessarily Bosch).
