What is a Coil-On-Plug (COP) system?

A Coil-On-Plug system means each spark plug has its own ignition coil mounted directly on top of it. These Moroso wires connect from that coil to the spark plug, bypassing the need for a distributor and traditional spark plug wire routing.

Are these wires suitable for high-performance applications?

These wires feature a high-resistance core and silicone construction, which are standard for reliable spark delivery. For highly modified or racing applications, always consult manufacturer recommendations for specific wire requirements.

What does the 90-degree boot mean for installation?

The 90-degree boot on the spark plug end allows the wire to connect at a right angle to the plug. This is helpful for routing the wires cleanly and ensuring they don't interfere with other engine components, especially in tight engine bays.

About this part

Product Details

If you're working on your GM LS engine and need to replace the spark plug wires, this set from Moroso is a solid option. These wires are designed for Coil-On-Plug (COP) systems, meaning they connect directly from the coil to the spark plug without a traditional distributor. The 11-inch length and 90-degree boot make them suitable for routing around engine components and ensuring a secure connection at the plug.

Moroso uses a high-resistance core wire with a silicone jacket for durability and good electrical insulation. The boots are also made of silicone, which helps them withstand the heat around the engine. This set is black, offering a clean, understated look under the hood. They are designed to fit right and provide reliable spark delivery for your LS engine.
