Moroso 73696 Ultra Unsleeved Spark Plug Wire Set - 40

The Moroso 73696 Ultra 40 Unsleeved Spark Plug Wire Set delivers race-proven ignition performance for high-output engines. Moroso's Ultra 40 series is built with a 40 ohm-per-foot spiral-wound core that suppresses RFI/EMI interference while maintaining a strong, consistent spark to each cylinder — critical for maximizing power and engine efficiency.

Unlike sleeved variants, this unsleeved set is ideal for applications where maximum heat dissipation is preferred or where additional sleeving is not required, giving installers a clean, direct routing option.

Key Features:

• 40 ohm/ft spiral-wound core — reduces radio frequency and electromagnetic interference without sacrificing spark energy
• 8.65mm wire diameter — high-strand copper-spiral conductor for superior conductivity
• High-temperature silicone jacket — resists heat, oil, and abrasion for long service life
• Unsleeved design — straightforward installation without additional thermal sleeve bulk
• Moroso performance terminals — provide a solid, low-resistance connection at the distributor cap and spark plugs
• Designed and manufactured in the USA

The Moroso Ultra 40 series is a trusted choice among professional racers and performance enthusiasts who demand reliable, high-energy ignition under extreme conditions. MPN: 73696.
