About this part

Product Details

These Moroso Ultra 40 ignition wires are built with a 0.040 inch conductor, offering a solid path for your spark energy. They come with 8-inch blue sleeves to help protect them from the heat and abrasion found in the engine bay, especially around exhaust components. If you're working on a GM LS engine and need a reliable set of spark plug wires, these are a well-built option that can handle the demands of the platform.

The wires themselves are constructed to ensure a strong spark gets to your spark plugs, which is crucial for efficient combustion and consistent engine performance. The sleeving is a practical addition that adds a layer of durability, helping to prevent premature failure from heat soak or physical contact. Moroso has a reputation for making solid engine components, and this wire set is no exception.
