An igniter for a combustor of a gas turbine engine includes a body section mounted on a ball joint within a standoff cylinder. The standoff cylinder, in turn, is mounted on the casing of the combustor. An electrode tip, extending from the body section if tightly fitted into a hole in the combustor liner. The ball joint permits substantial transverse motion of the electrode tip to fit it through the hole during installation of the igniter, and to track the position of the hole if it should move relative to the casing due to differential thermal expansion during operation of the combustor. Seals between mating parts prevents the leakage of air from the interior of the casing.
