About this product
When air cleaner performance matters, the FEBI BILSTEIN 40504 delivers — built to the same dimensional and material standards as the original part it replaces. The part is built to the following specification: Height [mm]: 559 mm, Inner Diameter [mm]: 190 mm, Outer Diameter [mm]: 282 mm, Filter type: Stainless Steel. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. This part supersedes original equipment references: 024.151, 11291 031, 154705511330, 252013 and 51 more. Matching these numbers confirms a like-for-like replacement with no loss of function.

Replacing worn components on schedule preserves your vehicle's safety, reliability, and resale value — and aftermarket parts from established brands deliver OEM-equivalent performance at a fraction of the dealer price.
