MSD 32819 Super Conductor Spark Plug Wire Set, Red – High EMI Suppression

Rugged, purpose-built spark plug wires

MSD's 32819 Super Conductor Spark Plug Wire Set combines an 8.5mm synthetic and silicone jacket with an extra-heavy glass braid and a dielectric insulator. This thoughtful construction guides current precisely to each spark plug, helping the system stay reliable under heat, vibration, and dusty under-hood environments. The result is a wire set that feels sturdy in hand and performs with confidence during spirited drives and routine maintenance alike.

Engineered for dependable delivery, the design emphasizes both protection and performance. The outer jacket shields the conductor, while the dielectric insulator helps maintain signal integrity across a range of operating conditions. The result is a set that feels resilient when installed and gives a sense of durability during everyday use.

• Stainless steel terminals feature dual crimp tabs to grip the conductor and outer jacket separately, reducing wear at connection points
• Dual crimp stainless steel terminals provide secure, corrosion-resistant ends
• Red wires paired with grey boots assist quick orientation during installation
• Dupont Kevlar core adds tensile strength to handle engine vibration and road use

EMI control and conductor design

The helically wound conductor core delivers only 40–50 ohms of resistance per foot, while the winding packs 40 feet of conductor into a single foot of wire. This layout supports EMI suppression without compromising spark delivery, helping maintain stable engine performance in demanding environments.

Durability and materials come together for lasting performance. The combination of the silicone jacket, glass braid, and dielectric insulator is chosen to stand up to heat, oil, and road debris, while the Kevlar core enhances strength under load. These features are designed to give you a sense of reliability during every drive, showroom event, or weekend project.

Vehicle fitment and warranty

• Designed to fit 1998–2002 Chevrolet Camaro, 1997–2004 Chevrolet Corvette, 1998–2002 Pontiac Firebird, and 2004 Pontiac GTO
• MSD Ignition warrants the product free from defects in materials and workmanship under normal use for one year from purchase when properly installed

Usage notes for enthusiasts

These wires are built for performance-minded enthusiasts who want a durable, reliable path for spark delivery with the potential for EMI handling improvements. They are not a guaranteed upgrade, but many users find the combination of materials and construction to be a meaningful upgrade for demanding daily driving or weekend projects. For best results, ensure proper fitment to your ignition system and vehicle year/model, and consider professional installation if you are unsure about the process.
