Frequently Asked Questions

Why does an air suspension kit include engine air filters?
Many W166/X166 owners perform their major suspension overhauls at the same mileage interval as their major engine service. This specific kit bundles the OM642 V6 Diesel engine air filter set (A6420940000) along with the air suspension compressor and valve block to provide a highly convenient, all-in-one maintenance package.
Does this kit include the small compressor intake filter?
Yes. While the primary part number A6420940000 refers to the large diesel engine filters, this complete bundle also includes the small, dedicated inline air filter, rubber hoses, and clamps that attach directly to the Airmatic compressor. This ensures your new pump only ingests clean, moisture-free air.
Do I need to replace the valve block and compressor at the same time?
Absolutely. When an old compressor fails, it often sends microscopic metallic debris and excess moisture through the air lines directly into the valve block. If you only replace the compressor, the contaminated valve block will restrict airflow and cause the brand-new pump to fail prematurely. Replacing them together is the only way to guarantee a long-lasting repair.
Will this kit fit my gasoline ML350 or ML63 AMG?
The Airmatic Compressor (A1663200104) and Valve Block (A2123200358) are universally compatible with all Airmatic-equipped W166/X166 platforms (both gas and diesel). However, the included Engine Air Filters (A6420940000) are engineered strictly for the OM642 3.0L V6 Diesel engine found in the BlueTEC models.
