1. A torch igniter for a combustor of a gas turbine engine, the torch igniter comprising:
an igniter body disposed within a high-pressure case of the gas turbine engine and extending primarily along a first axis, the igniter body comprising:
an annular wall surrounding the first axis and defining a radial extent of a combustion chamber therewithin; and
an outlet wall disposed at a downstream end of the annular wall, and defining a downstream extent of the combustion chamber, the outlet wall including an outlet fluidly communicating between the combustion chamber and an interior of the combustor;
an igniter head removably attached to the igniter body at an upstream end of the annular wall, wherein the igniter head defines an upstream extent of the combustion chamber, and comprises:
an ignition source extending at least partially into the combustion chamber; and
a fuel injector configured to inject fuel into the combustion chamber with an orientation impinging on the ignition source
wherein the igniter head extends through the high-pressure case and at least partially outside of the high-pressure case.
