How does the ST-4239 improve ignition performance and reliability?

These wires use a conductor and diameter tuned for strong spark delivery while the silicone outer sleeve resists high heat and abrasion commonly found around exhaust and engine hot zones. Corrosion-resistant terminals maintain secure electrical contact over time, reducing misfires caused by poor connections.

• 7mm diameter conductor for consistent spark transfer across each cylinder.
• Silicone boots and sleeves designed for thermal and mechanical durability.
• Premium snap-lock terminals that click into place for secure connections.

What should I expect during installation and fit confirmation?
