MSD 31659 Super Conductor Spark Plug Wire Set Small Block Chevy Socket Distributor Cap

The MSD 31659 Super Conductor Spark Plug Wire Set is a custom-fit performance ignition wire set designed for Small Block Chevy engines equipped with a socket-style distributor cap. MSD's Super Conductor series is engineered to deliver maximum spark energy to the plugs while suppressing electromagnetic interference (EMI) that can disrupt modern vehicle electronics and engine management systems.

Key Features:

• Ultra-low resistance – Super Conductor wire cores provide only 40–50 ohms per foot of resistance, ensuring maximum voltage transfer to the spark plug
• EMI/RFI suppression – Spiral-wound core design effectively suppresses electromagnetic and radio frequency interference without sacrificing spark energy
• 8.5mm wire diameter – Heavy-duty construction with a high-dielectric silicone jacket rated to withstand extreme underhood heat
• Custom-fit design – Pre-cut and terminated to exact lengths for a clean, rattle-free installation on Small Block Chevy applications with a socket-style distributor cap
• High-temperature boots – 90-degree or straight boots (as applicable) provide a secure seal at both the distributor cap and spark plug ends
• Street and race ready – Suitable for naturally aspirated, supercharged, and nitrous-assisted Small Block Chevy builds

MSD's Super Conductor Spark Plug Wires are a direct bolt-on upgrade over factory ignition wires, offering measurably better spark delivery and long-term durability. The set is compatible with MSD and OEM-style socket distributor caps, making them an ideal complement to any MSD ignition system upgrade.
