Spark Plug Wires
It’s impossible to overstate the importance of your Corvette’s ignition system. Keeping each component in as-new condition is critical to maintaining performance on a stock car, and upgraded ignition coils, plug wires and spark plugs can help your car take advantage of fuel/air and engine enhancements.
Of the three main external ignition parts, your Corvette’s spark plug wires live the hardest life. They’ve got to contain tens of thousands of volts of ignition energy, deliver it perfectly every time AND withstand underhood heat just a few inches from the exhaust manifolds. Add in headers and forced induction and the job gets exponentially more challenging.
At Vette Lab, our preferred solution to maintain maximum spark is to use premium spark plug wires AND replace them regularly. “Of COURSE that’s your solution – you sell Corvette parts,” you say, which is a valid point. However, we’re also in the business of maximizing power on customer cars, and plug wires are simply not the place to economize. You do the math and make the best decision for your car and situation.
Speaking of, what constitutes regular replacement? In our experience it depends on your Corvette and how you use it. Naturally aspirated (ie: non Z06/ZR1) cars simply street-driven can see wires last years and tens of thousands of miles before heat and the ozone from the air breaks them down. At the other extreme, heavily modified supercharged Corvettes regularly banging up against redline may see heat bake the wires in a year or less. Most of our cars fall somewhere between these two extremes.
Vette Lab offers three levels of spark plug wires to suit a variety of needs and budgets.
