Universal Spark Plug Wire Set. The Holley EFI Universal Cut-to-Fit Spark Plug Wire Set with Black boots is engineered for high performance and versatility within GM LS engine platforms. This set includes spark plug wires pre-assembled with terminals and boots at the spark plug end, while the coil end remains unterminated for tailored length customization, allowing a precise and clean installation to suit different engine setups.
Construction and Performance. Each wire features an approximately 8mm diameter stainless steel core wrapped in durable black silicone boots that provide excellent heat resistance and longevity. The wires maintain low resistance of about 350 Ohms per foot to support reliable ignition and feature very high electromagnetic interference (EMI) noise suppression, enhancing overall engine performance and reducing ignition noise.
Installation. Installation is straightforward, thanks to the cut-to-fit design which eliminates the need for drilling or additional modifications. Locking dual crimp terminals securely connect at the spark plug end, ensuring a firm electrical connection, while the unterminated coil end allows customization of wire length to best fit the vehicle’s coil packs.
Application. This wire set is designed to fit GM LS engines spanning models and sizes including 4.8L, 5.3L, 5.7L, 6.0L, 6.2L, and 7.0L V8s. It is compatible with 1998-2015 GM LS-based V8 Camaros and other vehicles utilizing GM Gen III/IV LS engines. It is suitable for use on emissions-controlled vehicles as well as racing applications, ensuring broad usability across emission requirements.
