Keep your engine running smoothly with fresh ignition components, such as spark plugs and wire sets. Over time, spark plugs begin to develop a layer of carbon buildup, which reduces the strength of spark output and reduces horsepower. A fresh set of NGK spark plugs is a great way to bring back missing power and torque from your LS1, LS2, LS3, LS6, LS7, or LS9 engine. Upgrading spark plug wires is a simple way to increase spark output, as many aftermarket solutions use larger wire and better material to conduct electricity. JDP Motorsports also carries the highest-performing plug wires from Taylor and Granatelli, but we don't stop there. To prolong the life of your plug wires, we offer these with thermal socks, which protect them from high temperatures and reduce failures.
