Keep your 3.9L or 4.0L V8 firing cleanly with the Motorad 1IC137 ignition coil, engineered for select Jaguar S-Type, Ford Thunderbird, and Lincoln LS applications from 1999-2006. This coil is built to meet or exceed OEM specifications, with ETP grade copper windings that stand up to underhood heat while maintaining strong voltage conductivity. A heat-resistant magnet helps deliver consistent voltage output across your engine's full speed range, supporting smoother starts and steady performance. Preapplied dielectric grease simplifies installation, saving time and mess in the bay. Manufactured at ISO TS16949 certified facilities, this coil reflects Motorad's commitment to quality engine management parts. It's backed by a limited lifetime warranty, giving you confidence in your purchase. Note that each application requires eight coils, so plan your order accordingly for a complete, dependable ignition refresh.
