The wires are numbered for clear cylinder identification, and the coil wires are color-coded to prevent mistakes during reassembly. The terminal ends feature positive-locking stainless steel construction, which provides a tight fit and resists separation caused by engine vibration. These features turn what could be a frustrating task into a manageable project for a weekend mechanic.
The primary consideration here is weight and cost compared to single wires. At over a pound, this is a substantial piece of equipment, but that heft comes from the heavy-duty materials used to protect the internal wiring. While it requires a full set purchase, the comprehensive protection and ease of installation make it a superior choice for maintaining a high-performance engine over the long term.
The increased thickness allows for even better conductivity and greater physical durability against abrasion. Like its smaller sibling, it includes two coil leads and comes with numbered wires and color coding to simplify the installation process.
