Arnott's air suspension compressor P-4341 for the 2014-2018 BMW X5 (F15) and the 2015-2019 X6 (F16) is a direct replacement for the original OE compressor from BMW. The compressor comes complete with a mounting bracket, integrated air dryer and electrical connectors for a fast plug and play installation. The most common cause of compressor failure is a leak in the air suspension system such as the rubber air springs.
