Wiring any high performance application can present any number of installation challenges. One of the challenges we often encounter is extreme temperature, be it from header tubes, turbo manifolds, or other potential sources of heat. Keeping your wiring safe is critical to ensure your engine and or electrical system continues to function as desired. Our new Nomex (R) Holley EFI Split Loom is engineered specifically to protect your investment from these high temperature conditions. This Nomex (R) Split Loom has an operating temperature range from -76F to +392F, and is self-wrapping, making installation quick and easy.
