The DEI Plug Wire Sheath 4-pack is an affordable and effective way to protect your ignition wires and boots from the extreme temperatures found in modern engine bays. These 3/4in x 6in sleeves are constructed from high-temperature glass fiber material bonded to a reflective aluminized outer layer, providing a robust barrier against damaging radiant heat.
Heat is the primary enemy of ignition wires, causing insulation to harden, crack, and eventually fail, leading to engine misfires and poor performance. By installing these protective sheaths, you ensure your ignition system remains reliable under high-load conditions. The 4-pack provides enough coverage for a standard 4-cylinder engine or can be combined for larger setups. Their durable construction ensures they can withstand the harsh under-hood environment, including exposure to oil and road debris. Whether you are running headers or a stock manifold, these sheaths are a simple upgrade that pays dividends in engine reliability. Trust GGCRACING for all your ignition and thermal protection needs.
