The cabin air filter in a BMW 523 is located inside the passenger side compartment. You'll need to remove the panel under the glove box using an E20 spline tool to reveal a small box. After removing the cover plate beneath this box (also requiring an E20 spline tool), you'll find the filter. The cabin air filter helps absorb dust particles, alleviates respiratory discomfort, reduces irritation for allergy sufferers, enhances driving comfort, and protects the air conditioning cooling system. The BMW 523 is a mid-to-large luxury sedan equipped with a 2.0T 184hp L4 engine producing 135kW maximum power and 290Nm peak torque, paired with an 8-speed automatic transmission.

What kind of glasses can prevent high beams?

Currently, there is no type of lens that can block direct light, as blocking it would render the glasses opaque, making it impossible for the driver to see objects outside. More details are as follows: 1. As for the so-called 'anti-glare glasses' available on the market, they cannot prevent high beams. These glasses can only reduce the glare around direct light, minimizing visual interference, but the effect is limited because high beams are not glare. 2. When driving at night and encountering oncoming vehicles, it is essential not to use high beams, as this is highly uncivilized behavior. You must switch back to low beams in advance when meeting another vehicle; otherwise, it will impair the oncoming driver's vision and pose significant safety risks.
