Key Features:

• Silicone insulation: Blue silicone insulation gives strong dielectric strength. The outer jacket is built to withstand temperatures above 250°C.
• 7.00 mm insulation outside diameter
• Stainless steel terminals: They hold tightly for positive connections over the life of the set.
• Variable-pitch magnetic core: A premium alloy winding over a ferrite magnetic alloy coating gives low resistance. It also suppresses radio and electrical interference.
• Cylinder lead ID: Identification tags, where possible, make installation easier.
• Specific fit: It is engineered for a direct-fit installation. It does not include wire separators.
• Limited lifetime warranty: See the package for details.

Fresh, high-quality ignition wires help keep spark delivery consistent, which supports smooth starting, steady idle and reliable engine performance. The wires are designed as a direct replacement for the original set.
