Hi-Perf Coil-Near-Plug Ignition Wire Connector Kit

The Granatelli Motorsports 28-1545S-R is a high-performance ignition wire connector kit engineered to elevate your vehicle's performance by maximizing power delivery, improving fuel efficiency, and enhancing overall engine output. This direct OEM replacement exceeds stock specifications and is OBD-II computer safe, designed to increase power to the spark plug by up to 400 percent over stock. Featuring a zero Ohm resistance core and a patented protector ring, these wires ensure optimal energy transfer and eliminate RFI/EMI interference, providing a clean spark signal. The construction includes high-temperature silicone boots and an 8mm jacket reinforced with fiberglass braid, rated to withstand temperatures up to 500 degrees Fahrenheit. Solid stainless connector cables with snap-lock spark plug connectors ensure durability and reliable connections. This kit is ideal for use with aftermarket headers and/or turbocharger systems, offering potential horsepower gains of up to 15 HP on naturally aspirated engines and up to 35 HP with forced induction (supercharger, turbocharger, or nitrous). Average gains on stock motors are reported at 5 HP naturally aspirated and 12-15 HP with factory forced induction. The wires are compatible with all fuel injection systems and suitable for both street and race cars. The Granatelli 28-1545S-R is a direct fit for GM LT1 6.2L V8 engines from 2014-2023, and also compatible with LS series engines (LS1-LS7, LSX, LQ4, LQ9, etc.), and works with naturally aspirated, turbocharged, or supercharged applications. Installation is straightforward with a pre-assembled, plug-and-play design requiring no trimming or splicing. The wires are proudly made in the USA.
