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

Granatelli GM LS & LT 0-Ohm 10" Red High-Temp Spark Plug Wires w/ Kevlar Boots – 28-1545HTRB

Upgrade your GM LS or LT ignition system with the Granatelli Motor Sports 28-1545HTRB 0-Ohm High-Performance Spark Plug Wire Set. Designed to transfer maximum available ignition energy from the coil directly to the spark plug, these wires are a simple performance upgrade for stock, modified and high-horsepower applications.

Each wire measures 10 inches from boot end to boot end and features red high-temperature silicone sleeves with Kevlar spark plug boots for added protection around headers and other high-heat exhaust components.

MORE SPARK. MORE POWER.

DYNO-TESTED GAINS ON GM V8 POWER

Granatelli ignition is proven on the dyno. In LSX Magazine's Project C700 test, a ProCharged LT1 Corvette gained 19.26 rwhp and 18.73 lb-ft after switching to Granatelli coils and 0-ohm coil-near-plug wires, with nothing else changed. See the LSX Magazine dyno test. Results vary with the engine, tune and combination.

Easy Bolt-On Performance: Remove your existing plug wires and replace them with the Granatelli 0-Ohm wires. No complicated ignition conversion is required, making this one of the simplest performance upgrades you can make to your LS or LT ignition system.

Built for High-Heat Applications

Aftermarket headers, turbo systems and performance exhaust components can expose spark plug wires to significantly more heat than a factory exhaust system. The red high-temperature silicone sleeves and Kevlar boots provide additional protection in these demanding environments while giving your engine bay a clean performance appearance.

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 sleeves and Kevlar boots provide increased heat protection, but the wires should still be routed with proper clearance from headers and other extremely hot exhaust components.
