Ultra 40 Plug Wire Set SBF 302 Un-Sleeved Blk

The Ultra 40 Plug Wire Set SBF 302 Un-Sleeved Black from Moroso is a precision ignition system engineered for small-block Ford 302 engines demanding reliable spark delivery under demanding conditions. Built for performance enthusiasts, engine builders, and field-tested operators who require consistent ignition timing in high-vibration environments, this plug wire set eliminates weak firing points that compromise engine responsiveness. The un-sleeved configuration reduces electromagnetic interference while maintaining durability across extended duty cycles, making it ideal for both street and competitive applications where spark integrity directly impacts engine performance and reliability.

Each wire in the Ultra 40 set is engineered with low-resistance conductors that minimize voltage loss from coil to spark plug, ensuring maximum energy transfer with every combustion cycle. The un-sleeved black design provides superior heat dissipation and vibration resistance compared to standard factory wiring, critical factors in high-output engines where thermal stress degrades conventional ignition systems. Moroso's manufacturing standards ensure consistent core construction and terminal crimping that withstand engine bay temperatures and mechanical shock, preserving firing reliability across the entire RPM range without signal degradation or arcing.

This plug wire set is purpose-built for small-block Ford 302 engines, including the SBF 302 platform found in performance vehicles and marine applications. Installation requires no modifications to existing distributor or coil configurations, making field replacement straightforward during maintenance cycles or engine rebuilds. The compact dimensions and lightweight construction (2.315 lbs) ensure hassle-free fitment in tight engine compartments, while the un-sleeved configuration allows operators to inspect wire condition and terminal connections without disassembly. Recommended for anyone upgrading from OEM wiring or seeking measurable improvements in cold-start response, throttle reaction, and sustained high-RPM stability.
