Reliable ignition starts with quality spark plug wires, and Moroso's Ultra series delivers performance you can count on for the Ford 351W small block. Built in the USA and backed by Moroso's decades of motorsport experience, these 135-degree boot wires fit the 351W without the guesswork of custom cutting or routing. Wire lengths are pre-cut and ready to route cleanly from distributor to plug on the first attempt.
Pre-measured lengths eliminate fitment frustration. The set includes one coil wire at 36 inches and seven plug wires cut to exact lengths: one at 29 inches, one at 33 inches, two at 32 inches, one at 28 inches, one at 26 inches, one at 34 inches, and one at 36 inches. Each wire routes to the correct cylinder without excess slack or tension.
135-degree boots clear tight header and valve cover clearances. The angled boot design lets wires exit the plug at a shallow angle, reducing stress on the boot-to-terminal connection and making routing around tight engine bay obstacles straightforward on 351W builds.
Configurable to match your ignition setup. These wires are available in HEI or non-HEI distributor cap configurations, sleeved or unsleeved for added heat protection, and in black or red to suit a subtle or show-ready engine bay. Choose the combination that fits your build before adding to cart.
