14-23 GM LT1 6.2L Hi-Perf Coil-Near-Plug Ignition Wire Connector Kit w/Red Jacket - Granatelli Motor Sports

Keep the path from coil to plug short, clean and built for power. Granatelli 10-inch 0-Ohm wires combine compact routing with maximum available spark-energy transfer for performance-driven LS & LT builds.

The Granatelli 28-1545HTR 0-Ohm High-Performance Spark Plug Wire Set is engineered to minimize resistance between the ignition coil and spark plug while maintaining a compact 10-inch boot-to-boot configuration for clean, controlled routing.

Built with 8mm red high-temperature silicone insulation, these wires are designed for demanding street and performance applications where strong spark delivery, under-hood durability and a clean installation all matter.

SHORT PATH. FULL SPARK. MORE PERFORMANCE.

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 plug wires and install the Granatelli 0-Ohm set. The pre-assembled design and OE-style connectors make this a straightforward ignition upgrade with no custom crimping, trimming or ignition conversion required.

10" Length Keeps Routing Tight & Clean

The 10-inch boot-to-boot configuration is ideal for applications where the ignition coils sit close to the spark plugs. The shorter length helps eliminate unnecessary wire slack, keeps routing controlled and gives the engine bay a cleaner, more purpose-built appearance.

0-Ohm Performance From Coil to Plug

Your ignition coils generate the energy needed to fire the spark plugs. Granatelli's 0-Ohm conductor design is engineered to minimize resistance through the wire so the maximum available coil output reaches the plug. Strong, consistent ignition becomes increasingly important as RPM, cylinder pressure, boost and horsepower increase.

Built for High-Temperature Engine Bays

Headers, turbo manifolds and performance exhaust systems can dramatically increase temperatures around the spark plugs. The 8mm red high-temperature silicone construction is rated beyond 500°F and designed to provide dependable protection in demanding street, strip and race environments.

Compatible GM LS & LT Engine Families

Designed for compatible GM LS and LT applications using the appropriate 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 family 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 provides increased protection in demanding engine bays, but the wires should still be routed with proper clearance from headers and other extremely hot exhaust components whenever possible.
