The Autolite 5285 is a conventional copper-core spark plug designed for reliable performance in a wide range of engines. Its specifications are as follows:

Multi-hole nozzle configuration splits diesel fuel into micro-droplets, ensuring uniform mixing with air inside the cylinder.

comes with a pre-set gap of 1.1mm (0.043"), according to MurCal. While they are ready to install, it is always recommended to verify the gap, say CARRISE.

The versatility of the DENSO 5285 makes it a staple across several demanding industries. 1. Commercial Trucking and Logistics

: The 98% pure copper core provides superior heat dissipation and thermal conductivity. Copper's excellent electrical and thermal properties allow the spark plug to operate across an ultra-wide heat range, making it suitable for diverse driving conditions. Additionally, copper enables extended electrode projection, which positions the spark deeper in the combustion chamber for improved flame kernel development.

How does it stack up against the big names? The main competitors are and Bosch Double Iridium .

In the realm of diesel powertrain engineering, the DENSO 5285 sub-assembly series (often cross-referenced with the base part number ) represents a highly precise Common Rail Fuel Injection component. Technical Specifications & Engineering
