AMS Alpha Replacement Air Filter | Mercedes-AMG CLA45 / GLA45

The AMS Performance Alpha Replacement Air Filter (part number ALP.19.08.0002-1) is the dry media filter used in the Alpha performance intake for the Mercedes-AMG CLA45 and GLA45 with the 2.0L M133 engine. Use it to replace a worn or damaged filter, or keep a spare on hand for track days.

The filter uses a synthetic media made to be restored to near-new flow by simply blowing it out with compressed air at 30-40 psi from the inside out. There is no oil to apply and frequent washing is not needed. After exposure to harsh conditions you can deep clean it with a mild biodegradable degreaser such as Simple Green, rinse it, shake or blow out the water and let it dry for a full day.

Important: this filter is designed for the Alpha 4" billet adapter used in the Alpha intake system. It is not directly compatible with the factory airbox on its own. If you are starting from stock, choose the complete Alpha intake system or the filter and adapter kit.
