Ultra 40 Boot & Terminal Kit - 90 Degree

The MOROSO Ultra 40 Boot & Terminal Kit in 90-degree configuration delivers a complete spark plug terminal and boot assembly solution for high-performance ignition systems. This set of eight units is engineered for precision fitment and reliable electrical continuity in demanding engine environments where spark plug boot integrity directly affects ignition performance and engine reliability.

Constructed to Ultra 40 specifications with an 8.65 mm terminal diameter, each boot and terminal assembly in this kit features a 90-degree angle configuration designed to optimize spark plug wire routing in confined engine bay layouts. The right-angle design prevents excessive stress on spark plug terminals while maintaining optimal contact pressure and electrical resistance. Black polymer boot material provides dielectric insulation, heat resistance, and protection against degradation from oil, coolant, and corrosive engine environment exposure. MOROSO's manufacturing standards ensure consistent terminal-to-boot assembly alignment across all eight units.

This kit addresses the needs of engine builders, restoration specialists, and performance technicians who require verified OEM-spec or aftermarket replacement ignition components. The 90-degree boot configuration accommodates modern engine designs where traditional straight boots create routing conflicts or terminal stress points. Users installing complete ignition systems, replacing degraded spark plug boots on vintage or performance engines, or assembling custom engine packages will find this eight-unit kit reduces the need for multiple smaller purchases while ensuring matched boot and terminal specifications across all cylinders.

MOROSO has built a reputation for precision ignition components used in both street and competition engine applications. The Ultra 40 boot and terminal line represents a mid-range offering positioned between economy and premium ignition assemblies, delivering consistent quality without premium pricing. Compact and lightweight at 0.38 lbs total, the complete kit ships efficiently while maintaining protective packaging standards for terminal integrity.
