Product Details

NGK builds ignition components with long OE experience across domestic and import vehicles, and this wire set reflects that focus on replacement accuracy and operational durability. The NGK Spark Plug Wire Set 52052 is a specific application part, not a universal set, so fitment should be matched to the vehicle listing before installation. For drivers servicing a Ford Contour, Mercury Mystique, Mercury Cougar, or Mazda MPV, this wire set provides an OE-style replacement path for worn or damaged ignition leads.

This part cross-references Gates 52052 for the same application.

What It Helps Address

• Misfires caused by aged or damaged ignition wires
• Hard starting related to weak spark transfer
• Intermittent ignition noise affecting engine operation
• Cracked or heat-damaged wire insulation
• Uneven idle from inconsistent spark delivery

Installation Notes

Verify engine application and routing before removal of the original wires. Match each lead to the correct cylinder position and keep the wires separated from hot exhaust components and sharp edges. On the 2000-2001 Mazda MPV, confirm the early design and engine number note before ordering or installing. Use the existing wire routing and retainers where applicable to preserve proper separation and firing order.

Quality Assurance
