Common Problems This Part Can Address

• Weak or inconsistent spark transfer through aging ignition wires
• Cracked, hardened, or heat-damaged wire insulation
• Poor terminal contact at the spark plug or distributor/coil end
• Misfire symptoms caused by deteriorated OE-style wire construction
• Routing or clearance issues on vehicles that require 180-degree spark plug boots

Installation Notes

Verify the vehicle’s ignition wire routing, terminal style, and 8mm specification before installation. Match each lead to the original routing path to reduce crossfire risk and maintain proper separation from exhaust heat and moving components. On Buick LeSabre, Oldsmobile Cutlass Supreme, and Pontiac Firebird applications, confirm the female terminal ends and boot angle before final fitment.
