BWI Group 991-375-059-11 PADM Dynamic Hydraulic Engine Mount

The BWI Group 991-375-059-11 is a genuine OEM Porsche Active Drivetrain Mount (PADM) hydraulic engine mount designed for Porsche 911 (991) models equipped with the Dynamic Engine Mounts option (option code I140). This is the updated revision of the electro-magnetically controlled dynamic mount, superseding earlier variants in the 991-375-059-0x series.

Unlike conventional rubber motor mounts, this advanced hydraulic mount uses a built-in electromagnet to actively alter the characteristics of its internal fluid in real time. In comfort driving modes, the mount remains compliant to isolate engine vibration and NVH from the cabin, while sport driving modes command the mount to stiffen, reducing powertrain movement for sharper throttle response and improved handling balance.

Key Features:

• Active electromagnetic control — adjusts internal fluid damping characteristics on demand via the vehicle's drive mode selector
• Porsche Active Drivetrain Mount (PADM) technology — option code I140, compatible with Sport Chrono Package-equipped vehicles
• Updated revision — supersedes OEM part numbers 99137505907, 99137505908, 99137505909, and 99137505910
• Sold individually — two mounts required per vehicle for a complete replacement
• Genuine OEM part — manufactured by BWI Group, a leading advanced chassis technology supplier
• Left and right positions — fits both driver and passenger side mount locations
