Choosing the correct cap

Use LB05F with the exposed threaded terminal stud. Check the plug terminal before fitting; it is not the same connection as LB05E.

Match the complete cap code, terminal type and shape to the ignition system. A similar-looking cap may have a different connection or resistance.
