Ultra 40 Plug Wire Set SBF 351W HEI Black

The Ultra 40 Plug Wire Set SBF 351W HEI Black from MOROSO is designed for classic and modified small-block Ford 351W engines equipped with HEI distributors. This plug wire set is ideal for automotive enthusiasts and mechanics who require reliable spark delivery, particularly under high-RPM conditions. It is essential for ensuring consistent ignition timing in both street and performance applications.

MOROSO's Ultra 40 design incorporates suppression core technology that minimizes radio frequency interference while maintaining low resistance for optimal spark voltage transfer to the spark plugs. The black insulation not only provides a professional appearance but also protects against heat degradation and UV exposure, which are critical factors in engine bays where temperatures can exceed 200°F. This construction is intended to enhance the longevity of the product.

This plug wire set is particularly beneficial for 351W engine builders, restoration shops, and performance tuners working with HEI ignition systems. It ensures proper cylinder sequencing and routing clarity for the HEI distributor cap layout, making it a valuable addition for anyone upgrading or restoring their vehicle.
