14-23 GM LT1 6.2L Hi-Perf Coil-Near-Plug Ignition Wire Conn Kit w/Ylw Jacket/Blk Sleeve - Granatelli Motor Sports

Every spark counts. Granatelli 0-Ohm wires are built to help your LS or LT deliver the ignition energy your coils are already producing—without unnecessary resistance getting in the way.

The Granatelli 28-1545HTYB 0-Ohm High-Performance Spark Plug Wire Set is engineered to transfer maximum available ignition energy directly from the coil to the spark plug. Whether your engine is stock, naturally aspirated, supercharged, turbocharged or nitrous-equipped, these wires are designed to support strong and consistent spark delivery under load.

Each wire measures 10 inches from boot end to boot end and features yellow high-temperature silicone construction with Kevlar spark plug boots, giving your ignition system added protection around headers and other high-heat exhaust components while adding a bold performance look under the hood.

SEND THE SPARK TO THE PLUG — NOT INTO RESISTANCE.

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 set. No complicated ignition conversion, trimming or crimping is required, making this one of the easiest ways to improve spark delivery on a compatible GM LS or LT engine.

Why 0-Ohm Makes a Difference

Your ignition coils generate the energy required to fire the spark plugs. Granatelli's 0-Ohm conductor design is engineered to minimize resistance through the wire, helping deliver the maximum available coil output directly to the spark plug. This becomes increasingly important as cylinder pressure, boost and horsepower increase.

Built for High-Heat Engine Bays

Headers, turbo systems and performance exhaust components can create extreme temperatures around the spark plugs. The yellow high-temperature silicone construction and Kevlar boots provide added protection in these demanding areas while helping maintain reliable ignition-wire performance in street, strip and race applications.

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

Heat Notice: The high-temperature silicone construction 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 whenever possible.
