Overview

Constructed with a heat-resistant magnesium oxide rod, it protects the internal heating and regulating coils from vibration and combustion shock.
Show original supplier description
The NGK Metal Glow Plug (Y1033AS) is a premium replacement component engineered for diesel engines that originally utilized metal-type glow plugs. It features a robust design with a magnesium oxide core that acts as an efficient thermal conductor while shielding internal coils from vibration, shock, and heat. This construction ensures superior electrical insulation and a gas-tight seal against combustion chamber pressures. The metal composition is specifically formulated to resist carbon buildup and prevent short circuits over time. Additionally, the component supports constant afterglow temperatures to help minimize noxious emissions during the engine warm-up cycle. This glow plug is intended for use in diesel applications where an OE metal glow plug is specified. Compatibility is highly specific to the engine type; please verify your engine requirements before purchase.
