Product Description – Clock Spring KD3366CS0A / KD5166CS0A for Mazda CX3 / 2 / MX5 (14 Pin)

Direct Fit for Mazda Models with 14-Pin Connector
This clock spring is engineered specifically for Mazda CX3 (2018–present), Mazda 2 (2014–present), and Mazda MX5 (2015–present) that use a 14-pin connector configuration. It directly replaces OEM part numbers KD3366CS0A and KD5166CS0A, guaranteeing a perfect fit and reliable performance.

Important: Verify Pin Count
This clock spring features 14 pins. Before ordering, please confirm that your original clock spring has 14 pins and the connector shape matches. Some models may use different pin counts (e.g., 10-pin, 16-pin). If unsure, contact us with your VIN for verification.

Why Your Clock Spring Matters
The clock spring (also called spiral cable or airbag rotor) is a critical safety component located behind the steering wheel. It ensures continuous electrical connection as the wheel turns, enabling:

  • Proper airbag deployment in a collision
  • Reliable horn operation
  • Functioning of steering wheel audio, phone, and cruise control buttons

A faulty clock spring may trigger the airbag warning light, cause horn failure, or make multifunction buttons unresponsive. Replacing it with our high-quality unit restores full functionality and safety.

Quality You Can Trust

  • High-Purity Copper Ribbon: Ensures stable, interference-free signal transmission even after thousands of turns.
  • Flame-Retardant Housing: Durable engineering plastic that meets stringent automotive safety standards.
  • Rigorous Testing: Passed 300,000-cycle endurance test; operates flawlessly from -40°C to +85°C.
  • Centering Clip Included: Holds the spring in correct alignment during installation – simply remove after mounting.
