Arnott Industries Air Suspension Compressor P/N:P-3722
Arnott Industries P-4343 air suspension compressor for the 2018-2019 BMW 640i xDrive Gran Turismo supplies compressed air to the air suspension system.
A worn compressor can leave the car sitting low or struggling to fill the system. Leaking rubber air springs or air lines can be behind those signs too, and a leak in the system is the most common cause of compressor failure, so find out where the air is escaping before you buy a new compressor.
This Arnott Industries air suspension compressor is a direct OE replacement for the 2018-2019 BMW 640i xDrive Gran Turismo, and each car takes one.
