Kooks GM LS / LT Truck 11 mm Spark Plug Wires, Grey / Black - 750204

A matched wire set for your LS or LT truck build

The Kooks 750204 supplies eight grey and black spark-plug wires for the listed GM LS/LT truck, SUV and van applications. The truck-specific listing and OEM coil-position requirement help you choose the right set, while high-temperature silicone insulation and angled boots provide the construction detail for the refit.

SKU: 750204

Choose the truck application

This set covers the listed 1999-2023 Gen III, IV and V LS/LT truck, SUV and van applications with coils in their OEM locations. Do not treat it as interchangeable with the car set solely because the engine carries an LS or LT name.

Check the wire construction

The set uses 11 mm high-temperature silicone insulation, a spiral-wound copper core and 30 ohms per foot resistance. The SureGrip silicone boots are angled at 45 degrees at both ends. Route the leads with suitable header clearance during fitting.

Choose your colour and protect the boots

Prefer a different finish? The orange/black truck/SUV/van wire set has the same listed construction for the same application family and OEM coil locations. If your plug boots sit close to the headers, the eight-pack of Kooks heat sleeves adds protection around the boots. Check that your actual boots fit the 1-1/4" opening and keep the leads clear of the exhaust.
