Granatelli Motor Sports 28-1811HTY 0 Ohm Yellow CNP Wire Kit GM LS2 LS3 LS7 LSA

Vehicle Fitment

• GM 6.0L and 6.2L LS-Series V8 Engines: LS2, LS3, LSA, LS7, LS9
• Over 600 total vehicle fitments across GM cars and trucks equipped with the above engine variants

Fitment Notes

• Designed specifically for the 8-inch coil-near-plug (CNP) lead wire length configuration common to GM 6.0L and 6.2L LS-platform engines.
• Direct OEM replacement - plug-and-play installation requires no modifications and is OBD-II computer safe.
• Compatible with naturally aspirated, supercharged, turbocharged, and nitrous oxide applications.
• Ideal for use with aftermarket headers and turbocharger systems where higher heat tolerance is required.
• Standard boots are rated to 500°F. Optional 1,200°F boots are available separately for extreme heat applications.
• Compatible with all fuel injection systems including factory and aftermarket setups.

Features

• True 0-ohm resistance design - protected by US Patent No. 7,185,622 - ensures 100% of ignition coil voltage is transmitted directly to the spark plug with zero energy loss in the wire itself.
• Solid stainless steel conductor core provides the electrical pathway for zero-resistance energy transfer while maintaining structural durability across heat cycling and vibration.
• Patented EMI/RFI protector ring eliminates electromagnetic and radio frequency interference - producing RFI/EMI outputs that are lower than OEM factory wires and fully compatible with modern ECU and aftermarket tuning systems.
• Stainless snap-lock spark plug connectors deliver a secure, positive connection to each plug terminal, eliminating the risk of connection failure under vibration or high-output conditions.
• 8mm outer jacket constructed from high-temperature silicone with fiberglass-reinforced braiding resists temperatures up to 500°F - built to withstand the demanding thermal environments near headers, turbos, and high-output forced-induction setups.
• Bold yellow jacket color provides immediate visual identification of the ignition wire set in the engine bay and is a distinctive cosmetic upgrade over factory black wires.
• Reported power gains of up to 15 HP on naturally aspirated applications; up to 35 HP on supercharged, turbocharged, or nitrous-equipped engines. Average gains are 5 HP on stock N/A applications and 12-15 HP with factory forced induction.
• Increases spark plug energy delivery by up to 400% over stock wiring systems - ensuring more complete combustion on every cylinder firing event.
• Made in the USA by Granatelli Motor Sports, backed by over 70 years of motorsport and high-performance ignition engineering heritage.

Product Description

The Granatelli Motor Sports 28-1811HTY is a high-performance coil-near-plug (CNP) ignition wire connector kit engineered for GM 6.0L and 6.2L LS-series engines including the LS2, LS3, LSA, LS7, and LS9. Built around Granatelli's patented 0-ohm resistance technology (US Patent No. 7,185,622), these wires transmit 100% of the ignition coil's voltage directly to the spark plug - eliminating the energy losses that occur in conventional resistance-core ignition wires and ensuring a stronger, more consistent spark on every firing event. The result is measurable performance improvement across all engine states: average gains of 5 horsepower on stock naturally aspirated applications and 12 to 15 horsepower on factory forced-induction setups, with peak gains of up to 15 HP (N/A) and up to 35 HP on supercharged, turbocharged, or nitrous-equipped builds.

At the core of the 28-1811HTY is a solid stainless steel conductor that provides the zero-resistance electrical pathway, surrounded by Granatelli's patented EMI/RFI protector ring - which actively suppresses electromagnetic and radio frequency interference to levels below OEM factory wires. This makes the kit fully compatible with modern ECUs, aftermarket tuning systems, and OBD-II diagnostics without introducing any electrical noise into the vehicle's systems. The 8mm outer jacket is constructed from high-temperature silicone with fiberglass-reinforced braiding, rated to withstand temperatures up to 500°F under sustained operation - making it suitable for installations near aftermarket headers, turbos, and high-output forced-induction systems. Stainless snap-lock spark plug connectors provide a secure, positive connection at each plug terminal, immune to vibration-induced loosening common in performance applications. The bold yellow jacket is a distinctive upgrade that provides easy visual identification during engine bay inspections.

Installation is a direct plug-and-play OEM replacement requiring no modifications and no special tools - the 8-inch lead wire length is purpose-matched to the CNP configuration of 6.0L and 6.2L LS-platform engines. The kit is compatible with all fuel injection systems and covers over 600 vehicle fitments across GM's broad LS-equipped car and truck lineup. Standard boots are rated to 500°F; for extreme heat environments, optional 1,200°F boots are available separately. Made in the USA and backed by Granatelli Motor Sports' long history of precision ignition engineering, the 28-1811HTY is a straightforward, proven upgrade for any GM LS platform where maximum spark energy, zero interference, and long-term reliability are the priority.
