OEM BDTS-57-KOOA Steering Wheel Airbag Replacement For 2021 Mazda 3

This product is engineered to strictly match the OE BDTS-57-K00A specifications for the 2021 Mazda 3 (BP Platform), ensuring a seamless plug-and-play installation.

• Physical Fitment: The airbag cover features identical grain texture and clip positions as the original, ensuring zero-gap alignment with the steering wheel frame.

• Electronic Protocol: It utilizes a Dual-Stage deployment system. The connectors are precision-molded to interface perfectly with the OEM Clock Spring, preventing SRS (Supplemental Restraint System) fault codes or resistance errors.

• Deployment Integrity: The cover is designed with precise laser-scored tear lines to ensure reliable opening within 30–60 milliseconds upon activation.

To achieve OEM-level stability, the core components utilize the following industrial-grade standards:

• Inflator: Uses high-stability, non-azide gas generants that comply with ISO 26262 functional safety standards. The pressure curve is calibrated to match Mazda’s crash pulse algorithms.

• Cushion Material: The bag is woven from high-tenacity Nylon 6,6 (PA66). It features an internal silicone coating to manage thermal loads from the inflator gases and reduce skin abrasion during deployment.

• Parametric Testing: Every unit undergoes automated resistance testing of the initiator (squib) and airtightness checks to ensure long-term shelf life and instantaneous activation.

Our manufacturing process adheres to rigorous validation protocols to meet global safety requirements:

Environmental Stress Screening (ESS): Units are subjected to extreme thermal cycling (ranging from -35°C to +85°C) and high-humidity aging tests to ensure the chemical propellant remains stable in any climate.

Dynamic Deployment Testing: Batch samples undergo high-speed camera deployment tests to verify that the pressure rise and bag shape conform to ECE R94 or FMVSS 208 safety standards.

Traceability: Each assembly is marked with a unique serial number and QR code. This allows for full lifecycle traceability—from the raw material batch of the inflator to the final assembly date—meeting the stringent transparency needs of the automotive aftermarket.
