West Peterson Posted August 1, 2023 Share Posted August 1, 2023 I would say yes, for the Phantom II. They had distributor and magneto ignition, with 6 spark plugs on each side of the engine, thus they needed two per car. Different than the Phantom I twin ignition, which had its 12 spark plugs on the same side of the engine. Link to comment Share on other sites More sharing options...
