The coil assembly includes an electrical transducer member having an elongate portion and a head portion. The coil assembly also includes a sleeve structured and arranged to support and seal the electrical transducer member from an ambient environment. A first end of the sleeve defines a sealing groove. The sleeve also includes a shoulder portion defined at the first end. The shoulder portion of the sleeve is in an abutment relationship with the step in the cylinder head coinciding with an assembled state of the sleeve with the cylinder head. The coil assembly further includes a sealing member received within the sealing groove of the sleeve. The head portion of the electrical transducer member is sealed with the second end of the sleeve in the assembled state.
