99-23 GM LS2/LS3/LSA/LS7/LS9 Hi-Perf Coil-Near-Plug Wire Conn Kit w/Ylw Jacket/Blk Sleeve - Granatelli Motor Sports

When every inch of engine-bay space matters, excess spark plug wire only gets in the way. Granatelli packs maximum 0-Ohm spark delivery into a true 8-inch wire built for tight, high-performance installations.

The Granatelli 28-1811HTYB 0-Ohm High-Performance Spark Plug Wire Set gives GM LS applications a compact coil-to-plug connection without sacrificing ignition performance. The short configuration helps eliminate unnecessary wire slack while delivering maximum available ignition energy directly from the coil to the spark plug.

Each wire measures 8 inches from boot end to boot end and features yellow high-temperature silicone construction with Kevlar spark plug boots, combining serious heat protection with a bold race-inspired appearance.

LESS WIRE. LESS RESISTANCE. MORE SPARK.

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.

Built for Tight Engine Bays: At a true 8 inches boot to boot, these wires are made for applications where the ignition coil sits close to the spark plug. The shorter configuration helps reduce excess wire, clean up routing and create a more purpose-built installation.

Put Your Coil's Energy to Work

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

800°F+ High-Temperature Protection

Performance headers, turbo systems and modified exhaust systems can expose ignition components to extreme temperatures. The 8mm yellow high-temperature silicone construction and Kevlar boots provide added protection against heat and vibration while giving your engine bay a distinctive performance look.

Compatible GM LS Engine Families

Designed for compatible GM LS engines using the appropriate coil-near-plug layout and 8-inch boot-end-to-boot-end wire configuration.

Common LS Engine Sizes

Important Fitment Notice: These wires measure 8 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 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.
