Moroso Ultra Spark Plug Wires for GM LS Engines

Moroso Ultra spark plug wires are ignition wire sets made for GM LS-series engines that use coil-on-plug ignition. They replace the stock plug wires or upgrade them with a durable, ready-to-install set. The sets suit street, performance and racing builds, and each set is made to fit LS coil and spark plug connections. They are sold under names such as LS spark plug wire sets, coil-on-plug wires and ignition wire sets.

Key Features:

• Purpose-built for GM LS engines: Custom-fit construction for LS coil-on-plug applications. Boot styles and wire lengths are matched to the engine, coils and valve covers.
• Quality conductor: A stainless nickel alloy conductor is wound around a conductive core to carry the spark reliably.
• Heat-resistant jacket: High-heat EPDM and silicone insulation resists heat and flame. It also adds dielectric strength and protects against chafing and contaminants.
• Silicone plug boots: The boots withstand high-heat conditions. Snap-lock terminals give a secure, positive connection at the coil and plug.
• Sleeved and unsleeved options: Sleeved versions add protection from exhaust header heat, abrasion and contaminants.
• Easy installation: Wires are made to fit LS applications for a straightforward installation.

Moroso has been a trusted name in racing and performance parts for decades. Moroso Ultra wires give LS owners a dependable ignition wire upgrade that is built to handle the heat and vibration of demanding use.
