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

Tight engine bay? Short coil-to-plug distance? This is where an 8-inch performance wire earns its place. Granatelli 0-Ohm wires keep routing compact while delivering maximum available ignition energy to the spark plug.

The Granatelli 28-1811HTBB 0-Ohm High-Performance Spark Plug Wire Set is built specifically for GM LS applications that benefit from a shorter wire configuration. The compact design helps eliminate unnecessary wire slack while maintaining the spark delivery demanded by stock, modified and high-performance engines.

Each wire measures 8 inches from boot end to boot end and features black high-temperature silicone wire with black Kevlar spark plug boots for a clean appearance, secure routing and added protection around high-heat engine components.

SHORTER WIRE. DIRECT SPARK. SERIOUS 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.

Built for Tight Installations: The true 8-inch boot-to-boot length is ideal when the ignition coils are positioned close to the spark plugs. Less unnecessary wire means a cleaner installation with tighter, more controlled routing throughout the engine bay.

0-Ohm Spark Delivery

Conventional resistance-type spark plug wires can consume some of the ignition energy traveling between the coil and spark plug. Granatelli's 0-Ohm design is engineered to transfer the maximum available coil output to the plug, supporting stronger spark energy, efficient combustion and consistent performance under load.

Built for Heat, Vibration & Performance

Performance engines generate heat and vibration that can quickly expose the weaknesses of ordinary ignition wires. The 8mm black high-temperature silicone jacket and black Kevlar boots help protect the wire assembly in demanding street, strip and race environments while maintaining a clean, professional appearance.

Compatible GM LS Engine Families

Designed for compatible GM LS-series 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 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.
