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

If you're working on a Chevrolet Small Block engine and need to replace your ignition wires, this Moroso Ultra 40 set is a solid option. These wires are designed to handle the demands of a performance ignition system, ensuring a strong spark reaches your spark plugs for reliable engine operation. They feature a 90-degree boot on one end, which is common for HEI distributors, making installation straightforward in many applications.

Moroso built these wires with a focus on durability and performance. The Ultra 40 construction means they have a low resistance core, which helps deliver a hotter spark compared to stock wires. This can lead to improved throttle response and overall engine efficiency. The wires are also sleeved, offering an extra layer of protection against heat and abrasion, which is particularly useful in tight engine bays where wires can come into contact with hot components. The bright blue color adds a nice visual touch under the hood.

When installing these, pay attention to routing them away from exhaust manifolds and other heat sources to maximize their lifespan. The 90-degree boots are designed to fit snugly onto the spark plug and the distributor cap, so ensure a firm connection on both ends for optimal performance.
