Granatelli GM LS & LT 0-Ohm 10" Black High-Temp Kevlar-Boot Coil-Near-Plug Spark Plug Wires – 28-1545HTBB

Keep the spark strong, the routing tight and the engine bay clean. Granatelli 0-Ohm 10-inch performance wires deliver maximum ignition energy in a compact package built for serious GM LS and LT performance.

The Granatelli 28-1545HTBB 0-Ohm High-Performance Spark Plug Wire Set is engineered to transfer maximum available ignition energy directly from the coil to the spark plug, making it an excellent upgrade for stock, modified and high-horsepower applications.

Each wire measures 10 inches from boot end to boot end and features black high-temperature silicone wire with black Kevlar spark plug boots for added durability and heat protection in demanding engine bays.

MORE SPARK. MORE POWER.

GUARANTEED 5–10 HP GAIN

Naturally aspirated applications can see a measurable horsepower increase, while supercharged, turbocharged and nitrous combinations may see even greater gains.

Easy Bolt-On Performance: Remove your existing spark plug wires and replace them with the Granatelli 0-Ohm wires. No complicated ignition conversion, trimming or custom wire assembly is required, making this one of the simplest ways to upgrade the ignition system on a compatible GM LS or LT engine.

Compact 10" Length for Clean Routing

The 10-inch boot-to-boot configuration is ideal for applications where shorter spark plug wires provide a cleaner and more direct path between the ignition coil and spark plug. Proper wire length helps reduce unnecessary slack while keeping the engine compartment organized and professional-looking.

Built for High-Heat Applications

Aftermarket headers, turbochargers and performance exhaust components can expose spark plug wires to significantly more heat than a factory exhaust system. The combination of black high-temperature silicone construction and black Kevlar boots provides added protection for demanding street, strip and race applications while maintaining a clean, understated appearance under the hood.

Compatible GM LS & LT Engine Families

Designed for many compatible GM LS and LT engines using the correct coil-near-plug layout and 10-inch boot-end-to-boot-end wire configuration.

Common Engine Sizes

Important Fitment Notice: Engine code or displacement alone does not guarantee fitment. These wires measure 10 inches from boot end to boot end. Compare your existing wire length, coil location, spark plug boot configuration and routing before ordering.

Heat Notice: The high-temperature silicone construction and black Kevlar boots provide increased heat protection, but the wires should still be routed with proper clearance from headers and other extremely hot exhaust components whenever possible.
