Bentley Ignition Plugs.

The fitting of the terminals to the ignition plugs has caused the terminal of No. 1 cylinder plug to foul the distributor lead of No. 4 cylinder, which in time may probably burn through the insulation and cause a short.

The length of the plug requires reducing to give more clearance.
