Engineered for Australian operating conditions, this Bosch Glow Plug Set suits Toyota Hilux 2.8L Turbo Diesel models built from 2020 to 2022. Sheath diameter is 4.0mm and resistance is approximately 0.6 ohms at ambient temperature. The Steel element reaches operating temperature in around 3 seconds, cutting cold-start smoke and cranking time. Post-glow operation is supported, which keeps combustion stable during warm-up and reduces emissions. 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. Every unit is supplied new with a 24 Months warranty against manufacturing defect.
