Extreme Race Wires 12 Inch LS Spark Plug Wires

When you bolt a Gen III LS motor into a classic chassis, ignition wiring must deliver stable spark under any condition. The Extreme Race Wires 12 Inch spark plug wires hold only 25 ohms per foot of resistance to ensure crisp throttle response and consistent combustion. Advanced RFI suppression keeps electrical noise from interfering with engine management sensors. Silicone insulation rated for 600 F and 45 degree boots simplify routing around headers and help prevent heat damage over time.

Optimized 8mm Conductor for Superior Ignition Energy

The 8mm diameter core of these spark plug wires is designed to minimize voltage drop and maintain a consistent current path, ensuring your LS engine receives maximum spark energy with each ignition cycle. At just 25 ohms of resistance per foot, these wires support quicker discharge times that translate into sharper throttle response and more reliable combustion events. This level of electrical efficiency can reveal hidden horsepower gains and maintain peak engine performance under heavy load or high RPM conditions. Precision engineering of the conductor material provides a stable platform for race or street applications alike.

Advanced Radio Frequency Suppression for Engine Management Integrity

Built-in radio frequency interference suppression protects critical engine sensors and the ECU from stray electromagnetic signals that can disrupt ignition timing. By incorporating a specialized resistive core and shielding mechanism within each wire, Extreme Race Wires ensure interference is absorbed before it reaches control modules or communication lines. This feature is vital in modern LS-powered builds where sensitive knock and crank position sensors demand clean signals. The result is stable ignition timing and consistent engine feedback regardless of surrounding electronic noise.

Heat Resistant Silicone Insulation for Extreme Underhood Conditions

A silicone jacket rated to withstand temperatures up to 600 �F envelops the wire assembly, safeguarding against heat soak from headers and exhaust manifolds. This high density insulation remains flexible over time, resisting oil, ozone and chemical exposure that can cause hardening or cracking in lesser materials. By preserving the integrity of the conductor core, the jacket prevents performance-robbing shorts and electrical leakage even in tight engine bays. Long term durability is assured as the outer layer resists abrasion and environmental contaminants.

Strategic 45 Degree Boot Geometry for Effortless LS Swap Fitment

The molded boots feature a 45 degree angle to facilitate neat routing around exhaust headers and frame rails common to LS engine swap layouts. This geometry reduces stress on the wire ends and helps maintain a secure seal against moisture and debris at the plug interface. Each boot is engineered for a snug fit on GM LS spark plug wells and coil packs, delivering a true plug and play experience for custom installations. By matching the factory footprint, these wires streamline the conversion process and eliminate time-consuming alignment issues.

These wires ensure consistent ignition performance and easy routing for your LS swap.
