MSD 32889 8.5mm Super Conductor Spark Plug Wire Set Red Multi-Angle Boots

The MSD 32889 is a custom-fit 8.5mm Super Conductor spark plug wire set precision-cut to OEM specifications. Featuring MSD's legendary Super Conductor construction, these wires deliver an exceptional combination of ultra-low resistance and maximum EMI suppression — making them the go-to upgrade for performance-minded enthusiasts.

Key Features:

• Ultra-Low Resistance: Only 40–50 ohms of resistance per 12-inch length — the lowest of any helically wound spark plug wire
• Copper Alloy Conductor: Maximizes voltage-carrying capability, minimizing spark energy loss so more power reaches the spark plug
• Helical Winding: Over 40 feet of conductor is tightly wound into every single foot of wire around a ferro-magnetic impregnated center core
• EMI Choke Design: The helical winding combined with the ferro-magnetic core creates a highly effective EMI choke, keeping electromagnetic interference contained within the wire and away from sensitive vehicle electronics
• High-Performance Outer Sleeve: A proprietary blend of silicone and synthetic materials provides excellent resistance to high heat, abrasion, and tears
• Dual Crimp Terminals: Stainless steel terminals feature two separate crimps — one for the wire sleeve and one for the conductor — ensuring a more secure connection and reducing the risk of spark arcing
• Multi-Angle Boots: Custom-fit multi-angled silicone boots designed to match OEM routing for a clean, direct installation
• Red Jacket Finish: Bold red jacket for a clean, performance look under the hood
• Bolt-On Installation: Pre-cut and terminated to exact specifications for a straightforward, no-modification install

The MSD 32889 Super Conductor wire set is a direct bolt-on performance upgrade, engineered from the inside out to maximize ignition efficiency while protecting modern engine electronics from interference. UPC: 085132328895.
