MSD 32329 Super Conductor 8.5mm Spark Plug Wire Set - Red

The MSD 32329 Super Conductor Spark Plug Wire Set is an 8.5mm performance ignition wire set engineered to deliver maximum spark energy with ultra-low resistance and superior EMI suppression. Featuring factory-style boots and terminals, this set is custom pre-cut for a direct bolt-on fit.

Key Features:

• Ultra-Low Resistance: Less than 40–50 ohms per 12-inch length — the lowest resistance of any helically wound wire — ensuring more energy reaches the spark plug
• Copper Alloy Spiral Core: Over 40 feet of copper alloy conductor is tightly wound into every single foot of wire for outstanding conductivity and durability
• Ferro-Magnetic EMI Choke: The helically wound conductor combined with a ferro-magnetic impregnated center core creates a highly effective EMI/RFI choke, keeping interference inside the wire and away from sensitive vehicle electronics
• DuPont Kevlar Reinforced Core: The conductor core is wrapped with DuPont Kevlar material for increased tensile strength and long-term durability
• High-Heat Resistant Outer Sleeve: A proprietary blend of silicone and synthetic materials forms a heavy-duty outer jacket that resists high heat, abrasion, and tears
• Dual Crimp Stainless Steel Terminals: Stainless steel terminals feature dual crimp tabs — one gripping the outer jacket and one gripping the conductor separately — for a secure, reliable connection
• Factory-Style Boots: Pre-terminated with factory-style boots for a clean, OEM-quality installation
• Pre-Cut to Fit: Wires are cut to exact specifications for a direct, no-modification installation
• Emissions Legal: Legal for sale and use on emissions-controlled vehicles, non-emissions-controlled vehicles, and racing applications

The MSD 32329 Super Conductor wire set delivers the ideal combination of ultra-low electrical resistance and maximum EMI suppression — performance characteristics that are typically in direct conflict with one another in conventional wire designs. The result is stronger, more consistent spark delivery and reduced interference with modern vehicle electronics.
