Description
Toyota Aygo KGB10 and WNB10 (EU models, 2005-2014) with the 1.4 D-4D diesel engine (WNB10, 1ND-TV 1.4L) use glow plugs for reliable cold starts. The OEM part 19850-54050 heats the combustion chamber to 900°C in 5 seconds, reducing cranking time and white smoke in Kenya’s cool mornings. These self-regulating plugs last 80,000-100,000 km or 2-3 years. Replace all four plugs to ensure even heating and prevent engine damage. TUV-certified, they integrate with the glow relay for automatic operation in the 1.4L diesel variant.
