12-Inch LS Spark Plug Wires – Efficient Spark. Clean Fit. Bold Look.

Power and precision come together in Granatelli’s 12-Inch 0 Ohm Spark Plug Wires. Engineered for zero spark loss and built for high-temp environments, these wires offer an exact fit for LS engines where space is tight and performance can’t be compromised. The vibrant insulation gives your engine bay a clean, modern finish.

0 Ohm Resistance Delivers Maximum Spark Transfer

Thanks to a zero resistance core, these wires send full coil voltage directly to the plugs—ensuring optimized ignition timing, quicker starts, better throttle response, and more efficient combustion. Perfect for tuned and high-output LS builds.

Precision 12-Inch Fitment

Each wire is precisely measured at 12 inches from boot to boot, making it ideal for performance setups with tight space constraints, coil relocations, or coil-near-plug configurations that demand clean routing and consistent performance.

High-Temp Silicone

Wrapped in vibrant 8mm silicone, these wires are resistant to temperatures above 800°F and insulated against harsh under-hood conditions.

Noise-Free Spark with Spiral-Wound Stainless Steel Core

Enjoy full compatibility with modern ECUs and digital tuning systems, thanks to a spiral-wound stainless core that suppresses electromagnetic (EMI) and radio frequency interference (RFI).

LS Engine Compatibility – Plug and Play

Designed to directly fit GM LS engines including LS1, LS2, LS3, LS6, LS7, LS9, LQ4, LQ9, and others. OE-style connectors make installation quick and seamless—no crimping or modification required.
