The SA 1105×2 kit consists of two identical filter elements designed for installation in the standard air intake housings under the windshield of the BMW E39. Given the model's premium status, these filters not only provide mechanical air purification but also support the correct operation of the AUC (automatic air recirculation control) sensor, preventing window fogging and unpleasant odors in the cabin.

Why do E39 owners choose the SA 1105×2?
Cabin Health: Effectively filters pollen, soot, fungal spores, and fine road dust, ensuring clean air for the driver and passengers.

Climate control protection: Clean filters reduce the load on the heater motor and prevent contamination of the air conditioner evaporator.

Perfect geometry: Precisely crafted edges ensure a tight fit in the plastic housings, eliminating rattling and whistling at high fan speeds.

Easy installation: Replacement takes 5 minutes and requires no special tools—ideal for DIY service.
