Moroso Chevrolet Small Block Ignition Wire Set - Ultra 40 - Sleeved - HEI - 90 Degree - Black

This Moroso Ultra 40 ignition wire set includes everything you need to replace the spark plug wires on your Chevrolet Small Block engine equipped with an HEI distributor. The set comes with 90-degree boots for the spark plug ends, designed to fit snugly and ensure a solid connection. The wires themselves are black and feature a durable sleeving for added protection.

Moroso is known for well-built engine components, and this wire set is no exception. The Ultra 40 wires are constructed with a high-resistance core to help suppress radio frequency interference, which can cause misfires and affect engine performance. The sleeving offers protection against heat and abrasion, common issues in the engine bay. This set is specifically designed for HEI distributors, meaning the cap connectors are built to mate correctly with that style of ignition system, making installation more straightforward.

When installing, take your time to route the wires carefully to avoid kinks or sharp bends, and ensure each boot clicks securely onto the spark plug and the distributor cap. Proper wire routing is key to preventing cross-talk and ensuring the longevity of the wires.
