Ultra 40 Plug Wire Set SBF 302 Un-Sleeved Blk

The Ultra 40 Plug Wire Set SBF 302 Un-Sleeved Black from Moroso is purpose-built for small-block Ford 302 engines running high-performance ignition systems. This wire set addresses a critical need for engine builders and street-performance enthusiasts who demand reliable spark delivery under demanding conditions. Whether you're tuning a 302-powered street rod, vintage muscle car, or weekend bracket racer, precision ignition timing directly impacts throttle response, fuel economy, and overall drivability—making quality plug wires non-negotiable.

Moroso's Ultra 40 design features unsleeved construction, which eliminates electromagnetic shielding interference and allows maximum spark energy transfer to the combustion chamber. The black finish provides professional appearance while the un-sleeved configuration reduces capacitive resistance—a critical factor when running solid-core or high-output ignition coils. This design choice makes the set ideal for carbureted or fuel-injected 302 builds where voltage delivery consistency matters; the wire construction resists heat degradation and oil contamination common in tight engine bays. The compact 9.45 x 3.75 x 9.55-inch package ships efficiently while maintaining structural integrity.

Mechanics and engine builders restoring or modifying SBF 302 platforms will find this wire set compatible with stock and aftermarket 302 engine blocks, whether naturally aspirated or mild-boost applications. Installation requires basic mechanical knowledge—route wires away from exhaust manifolds and moving components, and seat boots firmly on both coil pack and spark plug terminals to prevent arcing. This set performs best paired with quality spark plugs, modern ignition modules, and clean distributor or coil-pack contacts; proper maintenance ensures years of reliable performance without misfires or cold-start hesitation.
