Kooks 10mm Spark Plug Wires - Grey w/ Black Boots (8 pc. Set)

When you're working on a Gen III, IV, or V LS/LT based truck, SUV, or van engine from 1999 to 2023, ensuring a strong spark is key to performance. These 10mm spark plug wires from Kooks Headers are built to handle the demands of these popular engines, especially if you've got a high-performance build or are working close to the exhaust headers.

These wires feature a high-temperature silicone insulation that can stand up to the extra heat often found around LS engines. The core inside is a spiral-wound copper, which helps maintain a consistent 30 ohms per foot resistance rating across the set. This consistent resistance is important for delivering a clean, strong spark to each cylinder. The boots on both ends are also made of high-temp silicone and are angled at 45 degrees, which is a smart touch that helps them clear headers and other components that can be tight on these trucks.

This set includes eight wires, enough for a full V8 engine. They come in a grey wire color with black boots, giving a clean, updated look under the hood.
