Item SKU: ALP-78552-78610-27480-27804-27750-2-KIT

Air Lift Performance ALP4 kit with dual compressors and front and rear Performance struts for the 2004-2011 BMW 3 Series E90 sedan, 2006-2013 E91 wagon/touring, E92 coupe, and E93 convertible. It fits AWD and RWD models, but does not fit M Series cars.

• Vehicle-specific suspension: Front and rear Air Lift Performance struts are included for the listed E9x chassis. This is not a universal bag-and-bracket setup.
• ALP4 management: A pressure-based system with an all-in-one manifold that houses the ECU, solenoids, and pressure sensors. Fewer separate management components to find space for.
• Controller: The ALP4 controller uses a 5-inch full-color touchscreen in an anodized aluminum case, along with four physical buttons for quick adjustments.
• Dual compressors: Two compressors are included for the air supply side of the system.
• Air line and hardware: ALP4 management includes 1/4-inch DOT air line, fittings, a water trap, wiring, and mounting hardware. This stuff covers the core management plumbing and electrical pieces.
• Fitment notes: Fits AWD and RWD E90, E91, E92, and E93 applications within the listed model years. M Series models are excluded.

The useful part of a vehicle-specific kit is that the front and rear suspension components are matched to the E9x layout instead of leaving you to piece together generic parts. ALP4 keeps pressure management in one manifold, and the dual-compressor setup is part of this kit. No guessing whether it is intended for AWD or RWD either, as both are covered here, provided the car is not an M Series.
