12-Inch High Performance LS Spark Plug Wires – Zero Resistance, Precision Fit, Maximum Spark
When your LS-powered build demands peak ignition performance and space-efficient routing, Granatelli’s 12-Inch 0 Ohm Spark Plug Wires deliver. Built to exacting specs, these ultra-reliable wires offer zero resistance, robust EMI shielding, and high-temperature durability—engineered for street, strip, or track.
Experience full voltage transfer from coil to plug without internal resistance. That means more responsive ignition, cleaner combustion, and a noticeable boost in throttle precision and overall engine output. Designed for demanding, high-performance environments.
Each wire measures a true 12 inches from boot to boot, giving you the flexibility to route neatly even in tight engine bays or custom coil configurations. Ideal for coil-near-plug, coil relocation, or custom LS engine layouts where space matters.
Outfitted with rugged 8mm black silicone jackets and ceramic boots, these wires are built to withstand temperatures exceeding 1000°F. Built for harsh under-hood conditions and extended high-load operation without failure or signal loss.
The stainless steel spiral core is designed to suppress EMI and RFI noise, ensuring optimal performance with sensitive aftermarket ECUs, tuning modules, and engine management systems.
Built for seamless integration with GM LS-series engines including LS1, LS2, LS3, LS6, LS7, LS9, LQ4, LQ9, and more. Installs easily with OE-style connectors—no cutting, splicing, or guessing required.
Engineered and manufactured in the USA, these wires are used by professional tuners, racers, and engine builders who need a wire they can trust lap after lap, mile after mile.
Granatelli Part #28-1629-CBB is a high-performance, zero-resistance ignition wire solution crafted to deliver consistent power, tight fitment, and elite spark energy transfer for LS engines where space is limited and output is critical.
