A compression resistant isolator disposed between a direct fuel injector and a cylinder head of an internal combustion engine provides thermal, or thermal and vibrational isolation therebetween. A plurality of radially spaced rigid axial support members provide axial load support to maintain proper direct fuel injector positioning within the cylinder head bore. Spaces formed between the rigid axial support members may have isolation materials positioned therein. The implementation of the isolator may reduce the operating temperature of a fuel injector for direct injection, which is critical to avoid injector tip plugging.
