Constructed with a durable 8mm jacket and fiberglass-reinforced braid, these wires are built to withstand high temperatures and resist common engine bay contaminants like oil and chemicals. They incorporate a patented protector ring that effectively eliminates RFI and EMI, while solid stainless steel connector cables and snap-lock connectors ensure a secure and conductive connection. The high-temperature silicone boots are rated to 500°F. These performance spark plug wires are versatile, working with all fuel injection systems and are ideal for use with aftermarket headers and turbocharger systems. Granatelli claims an increase of up to 15 horsepower for naturally aspirated engines and up to 35 horsepower for forced induction or nitrous systems.
