Bosch premium quality wire sets meet, and often exceed, the performance of the OE wire set they replace. Bosch premium wire sets feature opti-layer mag wire, and are pre-assembled, with no cutting required. Opti-layer mag wire features a stainless steel core that is reinforced with Kevlar and will not break down like carbon cores in many conventional plug wires.
The stainless core is sheathed in ethylene propylene diene monomer, inner insulation to stop voltage leaks, and then covered with a 100 percent pure silicone jacket for lifetime protection. Bosch premium quality wire sets deliver maximum voltage to the spark plug for a hotter, more powerful and longer spark which results in optimum engine performance while reducing the chance for misfire.
Bosch wire sets feature snug-fitting OEM-style silicone boots to ensure proper fit, function and appearance while providing extreme durability for long life. Wires are tightly crimped to the connectors to exceed OEM standards, providing worry-free installation and re-installation.
