FAST 295-2416 FireWire Big Block Chevrolet Under-Header Spark Plug Wire Set with Heat Sleeve

The FAST FireWire 295-2416 is a high-performance spark plug wire set engineered specifically for Big Block Chevrolet applications with an under-header routing configuration. Designed for performance and racing use, the FireWire wire set ensures maximum ignition voltage delivery from the distributor to the spark plug — completing the equation for a fully optimized ignition system.

At the core of the FireWire's design is a unique reactive conductor that delivers less than 25 ohms per foot of resistance — among the lowest available in performance spark plug wires. Lower resistance means more spark energy reaches the plug gap on every firing event, translating directly into more complete combustion and improved engine performance.

The reactive core design also serves a critical secondary function: effective suppression of electro-magnetic interference (EMI). By filtering the electrical noise generated within spark plug wires, the FireWire protects the ignition control module, EFI systems, and all other sensitive onboard electronics from interference-related issues.

To survive the harsh conditions found in high-performance engine bays, the conductor and core are sheathed in double-layered, pure silicone insulation. This construction provides excellent resistance to header heat, engine oils, and mechanical abrasion. The included heat sleeve provides additional thermal protection specifically suited for under-header routing. The silicone boots are rated to withstand temperatures up to 550°F, ensuring reliable performance even in extreme heat environments.
