These Genuine GM OEM spark plug wires (Part #12716289) are new take-offs removed from brand-new GM engines and have never been used. They include factory-installed heat shields and straight boots designed for optimal clearance and durability when paired with OEM exhaust manifolds. As true GM Genuine parts, they provide factory-correct fit, form, and function—ensuring reliable ignition performance and long service life. For modified vehicles running aftermarket tubular headers, consider upgrading to our Michigan Motorsports 45-degree boot spark plug wires for improved routing and heat management.
