99-23 GM 6.0L/6.2L LS2/LS3/LSA/LS7/LS9 Cars Hi-Perf Coil-Near-Plug Wire Conn Kit - Red - Granatelli Motor Sports

Upgrade the connection between your ignition coils and spark plugs with Granatelli 8-inch red 0-Ohm performance wires—designed to reduce electrical resistance and deliver more of your coil's available ignition energy directly to the spark plug.

The Granatelli 28-1811S-R 0-Ohm High-Performance Spark Plug Wire Set is engineered for compatible GM LS & LT coil-near-plug ignition systems. The compact 8-inch boot-to-boot length helps keep coil-to-plug routing short, clean and organized without unnecessary wire slack.

Unlike Granatelli's dedicated high-temperature and Kevlar-protected wire sets, the 28-1811S-R provides standard/base heat protection comparable to an OEM-style spark plug wire. Its primary performance advantage is the 0-Ohm conductor design, which minimizes electrical resistance between the ignition coil and spark plug.

LESS RESISTANCE. MORE AVAILABLE SPARK ENERGY.

GUARANTEED 5–10 HP GAIN

Granatelli 0-Ohm wires are designed to reduce electrical resistance so more of the ignition coil's available energy reaches the spark plug. Naturally aspirated applications can see measurable horsepower gains, while boosted or nitrous combinations may benefit even more.

Standard Heat Protection: The 28-1811S-R provides base heat protection similar to an OEM-style spark plug wire. This is not Granatelli's upgraded high-temperature or Kevlar-boot version. If your wires will be positioned extremely close to headers or other intense heat sources, choose one of Granatelli's dedicated high-temperature wire sets instead.

The Real Upgrade: 0-Ohm Performance

The key advantage of the 28-1811S-R is its 0-Ohm conductor design. Conventional spark plug wires use resistance that consumes part of the electrical energy produced by the ignition coil before it reaches the plug. Granatelli's 0-Ohm technology minimizes that resistance so more of the coil's available energy can reach the spark plug.

More Available Energy From Coil to Plug

Spark plug wires do not create additional ignition energy—the ignition coil does that. A performance wire improves the path between the coil and plug. By reducing resistance, Granatelli's 0-Ohm design helps minimize energy loss and provides a more direct electrical connection to the spark plug.

8" Length for Clean Coil-to-Plug Routing

The 8-inch boot-to-boot configuration is ideal for applications where the ignition coils are mounted relatively close to the spark plugs. The shorter length helps eliminate unnecessary wire loops and keeps the engine bay looking clean, organized and purpose-built.

Ideal for Street & Performance Applications

For vehicles with normal spark plug wire routing and adequate clearance from exhaust heat, the 28-1811S-R provides the protection expected from a standard performance wire while adding the primary benefit of Granatelli's 0-Ohm ignition technology.

Compatible GM LS & LT Applications

Designed for compatible GM coil-near-plug ignition systems using the correct 8-inch boot-to-boot wire configuration. Common LS-family applications include:

Common Engine Sizes

Important Fitment Notice: Part #28-1811S-R uses 8-inch wires measured boot end to boot end. Engine family or displacement alone does not guarantee physical fitment. Compare your existing wire length, ignition coil position, spark plug boot configuration, connector style and routing before ordering.

Heat Notice: This wire provides standard/base heat protection comparable to OEM-style spark plug wires. It is not intended to replace Granatelli's dedicated high-temperature or Kevlar-protected wire sets when the wire or boot must operate extremely close to headers or other intense heat sources.
