Built to original equipment form, fit and function, the Denso Glow Plug Set covers Isuzu MU-X 3.0L Turbo Diesel models built from 2020 to 2022. Post-glow operation is supported, which keeps combustion stable during warm-up and reduces emissions. The Ceramic element reaches operating temperature in around 4 seconds, cutting cold-start smoke and cranking time. Sheath diameter is 4.0mm and resistance is approximately 1.2 ohms at ambient temperature. Always replace glow plugs as a set and torque to 15 Nm; over-tightening will snap the element in the head. A failed glow plug commonly shows as hard starting below ten degrees and a flashing coil light on the dash. New stock, 3 Years / 60,000 km warranty, and dispatched from our Australian warehouse.
