NGK Glow Plug 90066

The CZ256 / 90066 ceramic glow plug combines a heating coil with a rugged ceramic sheath to provide higher temperatures and very short preheating times, thanks to excellent thermal conductivity. The heating coil is sheathed in silicon nitrite, a durable ceramic material, and the design remains compact to fit tightly in modern engines with limited space. This glow plug is designed to support reliable starts in diesel engines at low exterior temperatures, promote smooth engine running, and help reduce emissions. Key physical details include a hex size of 12 mm, M10 x 1.25 thread, overall length of 86.5 mm, heater tube length of 20 mm, and a terminal that is M4 threaded, with a marked voltage of 11 V. Note: observe the general fitting instructions before installation.
