Vehicle Application and Placement

The presented side airbag module is intended for installation in the front left seat. It is responsible for protecting the driver's torso in side impacts, working in conjunction with the vehicle's factory SRS system.

This part is dedicated to the seat in the Porsche Cayman 987C model, ensuring:

• proper fit to the seat structure, without the need for upholstery or frame modifications,
• compatibility with factory mounting points and wiring harness,
• preservation of the manufacturer-intended airbag deployment zone upon activation.

Technical Characteristics of the Module

The seat side airbag module is an integral part of the passive safety system. Its design has been developed by the vehicle manufacturer to:

• work with collision sensors and the airbag control unit,
• ensure controlled inflation within a precisely defined timeframe,
• maintain predictable vehicle behavior in a collision situation through proper driver protection.

As a component from the seats and benches category, the module is designed not to interfere with seat ergonomics while simultaneously meeting the safety and homologation requirements for the specific Porsche model.

Product Condition and Benefits of Choosing a Used Part

The offered module is a used part, sourced from dismantling. This type of solution is often chosen by informed users who expect:

• factory compatibility with the vehicle's system,
• preservation of original safety specifications,
• rational repair costs compared to purchasing a new part.

Choosing an original module from the aftermarket allows for maintaining the integrity of the SRS system, which is particularly important for post-collision repairs or when replacing a seat with another unit from the same model generation.

Why Choose an Original Porsche Seat Side Airbag Module

Using dedicated safety components in a Porsche is crucial for the proper functioning of the entire system. For a seat side airbag module, this means:

• maintaining the manufacturer-specified deployment parameters in an emergency situation,
• no need for mechanical or electrical adaptation, which is typical for universal aftermarket parts,
• compatibility with the seat and upholstery structure, reducing the risk of improper airbag deployment.

This solution is particularly recommended for professional accident repairs, interior restorations, and returning the vehicle to its factory-original condition.
