| - 2 - later plugs seem somewhat of an improvement but do not compare favourably as yet with the Bosch type of plug. I think, therefore, that we should still experiment with ignition plugs and try to obtain one which will overcome these troubles. It is a fact that we have obtained very good results with the air cooled "Mica" type Lodge plugs used on the Renault engines, with which we have so far had no failures. I suggest that a set of these plugs or similar type as made for car engines, should be tested on an experimental car. EP. {G. Eric Platford - Chief Quality Engineer} | ||
