Genuine Mercedes-Benz Air Drier 789-340-33-00

Very fast shipping, and very fresh product ( 2022) with expiration date to 2025, genuine MB desiccant priced half of my local MB dealer, fit perfectly, a great Amazon marketplace seller, highly recommended. You could buy a cheaper such from EU via Ebay, but will take at least a month of shipping, so I decided to buy from local NA market. Buying a silicon bead packs ( Dry and dry on amazon) will be much cheaper than buy such genuine filter/dryer, but that will void your battery warranty, so I don't want void mine and I will keep like this , for another 4 years until warranty r expires.

The thing comes in a foil pouch from France, take about 3 weeks, you need a special socket to unscrew the old one and then you screw the new one back in. Easy Peasy.

Don’t buy this drier is you own a 453. 453s don’t use the battery pack drier.

perfect fit. no need to lift car. seals tight with included rubber washer. just need a # 90 torx bit for removal & installation

Part was exactly what I wanted. It was a genuine and fresh Mercedes part.

It's the desiccant cartridge for the Smart ED.

Worked fine. I am happy.

This is an actual Mercedes-Benz part and is an exact replacement for my smart ED (451). It arrived very promptly and in original M-B packaging.
