Simple Bolt-On Ignition Upgrade: No LS swap, coil conversion or complicated ignition modification is required. These wires are designed as a direct replacement for compatible distributor-equipped GM applications, making them an easy upgrade for trucks, SUVs, vans and performance builds.
Put More Spark Energy at the Plug
```Conventional resistance-type ignition wires consume some of the energy traveling between the ignition system and spark plug. Granatelli's patented 0-Ohm technology is engineered to minimize that resistance while controlling electrical interference, helping deliver strong and consistent ignition performance throughout the RPM range.
```Built for Real-World Small-Block Performance
```Whether you're maintaining a daily-driven Vortec truck, upgrading a GM 350-powered SUV or building a street-performance small-block, the combination of 8mm construction, silicone boots and fiberglass reinforcement is designed to withstand the heat, vibration and demanding conditions found under the hood.
```Designed for GM Small-Block V8 Applications
```Part #28-1275S is designed for compatible Chevrolet, GMC and Cadillac applications using GM's traditional 5.0L/305 and 5.7L/350 V8 ignition configurations.
