Moroso Chevrolet Big Block Ignition Wire Set - Ultra 40 - Sleeved - Non-HEI - Crab - 90 Degree -Blue

These Moroso Ultra 40 ignition wires feature a 7mm conductor with a resistance of 40 ohms per foot, which helps ensure a strong spark reaches your spark plugs. The wires are covered in a blue, high-temperature silicone sleeve that can handle up to 1500 degrees Fahrenheit, protecting them from engine heat and abrasion. This set is specifically designed for Chevrolet Big Block engines that do not use an HEI distributor, featuring crab-style, 90-degree boots for a secure connection at the spark plug.

The Ultra 40 wire construction uses a helically wound copper conductor, which is less prone to RFI (radio frequency interference) than standard carbon core wires, helping to keep your electronics running smoothly. The 90-degree boots are designed to fit snugly onto the spark plug terminal, providing a reliable connection and preventing misfires. This set is a well-built option for those looking to replace or upgrade the ignition wires on their classic Chevrolet big block motor.

When installing these wires, ensure each boot clicks securely onto the spark plug terminal and the distributor cap terminal to prevent any loss of spark. Proper routing is also important to avoid contact with hot exhaust components.
