99-01 Cadillac Escalade 8Cyl 5.7L Performance Ignition Wires - Granatelli Motor Sports

Your classic GM small-block may be old-school, but its ignition system doesn't have to be. Granatelli 0-Ohm Performance Wires help put more of your ignition system's available energy directly at the spark plug for stronger, more consistent performance.

The Granatelli 28-1275S High-Performance Spark Plug Wire Set is designed for compatible GM 5.0L/305 and 5.7L/350 V8 applications, including many Vortec-powered Chevrolet and GMC trucks, SUVs and vans.

Featuring Granatelli's 0-Ohm resistance technology, durable 8mm blue wire construction, silicone boots and RFI/EMI suppression, this complete V8 wire set delivers a serious ignition upgrade while retaining straightforward OEM-style installation.

WAKE UP YOUR GM 350.

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.

Common Applications

Important Fitment Notice: Part #28-1275S is for compatible GM 5.0L/305 and 5.7L/350 traditional small-block/Vortec applications. It is not an LS or LT engine spark plug wire set. Always verify year, make, model, engine and ignition configuration before ordering.

Heat Notice: High-performance ignition-wire construction provides increased durability, but proper clearance from headers and other extremely hot exhaust components is still recommended whenever possible.
