Rich Ceramic Spark Plug Wire Set for LS3, LS4, LS7 Engines

The Extreme 9000 ceramic spark plug boots are designed to withstand extreme temperatures of up to 2,000°F, thanks to the 135-degree ceramic construction. This heat-resistant design, combined with the 8mm double silicone construction and a 600°F-rated black wire, ensures the wires can handle the demanding conditions of the engine bay without degradation or electrical issues. As a result, users can expect smoother operation, better throttle response, increased power output, and enhanced overall engine efficiency.

Featuring a 500 Ohms/foot ferro-spiral core, these spark plug wires offer the highest level of RFI/EMI suppression, minimizing energy loss and the electrical current reaching the spark plugs. This improvement in ignition efficiency and spark performance further contributes to the enhanced engine operation. The stainless steel plug terminals and the silicone jacket provide long-lasting durability, protecting the wires from the rigors of high temperatures, vibration, and exposure to oil and other contaminants.

This custom-fit spark plug wire set is designed to be a direct replacement for GM's Gen 4 LS3/LS4/LS7 engines, simplifying the installation process and ensuring proper connections. It is compatible with a wide range of Cadillac, Chevrolet, and GMC vehicles, including the Cadillac CTS (2006-2007) and Escalade ESV/EXT (2007-2008), Chevrolet Avalanche (2007-2008), Corvette (2005-2008), Express (2008), Impala (2006-2008), Monte Carlo (2006-2007), Silverado (2007-2008), Suburban (2007-2008), Tahoe (2007-2008), Trailblazer (2006-2008), GMC Envoy (2005-2008), Savana (2008), Sierra (2007-2008), Yukon (2007-2008), and more.
