Our Take

Best for: Best for DIY mechanics building or upgrading an 8-cylinder EFI engine.

The FAST Firewire 255-0082 wireset delivers a no-compromise spark plug wire for EFI engines. The 25 ohms/ft resistance is among the lowest, ensuring maximum energy reaches the plugs. The silicone-on-silicone construction and 550°F rated boots mean these wires handle engine bay heat better than most. The EMI filtering is a genuine benefit for fuel injection systems that are sensitive to electrical noise. These are cut-to-fit wires, so you need to measure, cut, and crimp the included terminals. That gives you a custom-length setup but requires patience and the right crimping tool. The 90-degree spark plug boots are common on many small-block and big-block V8s, but check your application. 11 and 25% off retail. For anyone building or upgrading an 8-cylinder EFI engine, these wires offer high-end features at a competitive price.

Price Analysis

At $29.12, this is 25% off the $38.93 list price and below the 90-day average of $36.11. It's an excellent time to buy, especially compared to recent pricing.
