The Mann suspension air compressor filter with part number 29106-08047674 is a critical component for maintaining the performance and longevity of air suspension systems in many late-model vehicles. While it may seem like a simple filter, using the correct replacement ensures your compressor runs clean and efficient. This guide explains what this filter does, which vehicles use it, and how to handle replacement.
What Is the Mann Air Compressor Filter 29106-08047674?
This filter is designed to fit the air suspension compressor on select vehicles equipped with an air ride system. Its primary role is to clean the air drawn into the compressor before it pressurizes the air springs or struts. By trapping dust, dirt, and other contaminants, the filter prevents debris from damaging sensitive internal components like the piston rings, valves, and desiccant.
Mann is an established OEM supplier for many European automakers, so this filter meets strict quality standards. The part number 29106-08047674 corresponds to the manufacturer's catalog reference. It typically consists of a paper filter element enclosed in a plastic housing, often with an integrated pre-screen.
Key Features
- High filtration efficiency: Captures particles down to a few microns.
- Durable construction: Designed to withstand temperature extremes and vibration.
- Direct replacement: Matches the original equipment specification.
- Easy to install: Usually clips or bolts into place without special tools.
Vehicle Compatibility
This Mann filter is primarily used on certain models from BMW, Land Rover, and possibly other luxury brands. It is most commonly associated with:
- BMW 5 Series (F10, F11, F18) – from about 2010 to 2017
- BMW 7 Series (F01, F02, F03, F04) – from 2009 to 2015
- BMW X5 (E70, F15) – certain years
- BMW X6 (E71, F16) – certain years
- Land Rover Range Rover (L322) – later models
- Land Rover Range Rover Sport (L320, L494) – certain years
However, fitment can vary by model year and optional equipment. Not every vehicle with air suspension uses this exact filter; some use a different part number. Always cross-reference your vehicle's VIN or the existing filter part number before purchasing.
Why Replacing the Air Compressor Filter Matters
The air suspension compressor works hard to maintain ride height and leveling. If the intake filter becomes clogged or saturated with moisture, the compressor must work harder, leading to:
- Reduced compressor lifespan
- Overheating
- Contaminated air entering the system
- Premature failure of air springs or valves
Replacing the filter at recommended intervals (typically every 50,000 miles or as part of major service) helps keep the system reliable. Some owners attempt to clean and reuse the filter, but because the paper element degrades over time, replacement is the safer choice.
How to Verify You Have the Correct Part
Before ordering a replacement, confirm compatibility:
- Locate the compressor unit: Usually under the vehicle near the spare tire well or behind a panel in the engine bay.
- Remove the old filter and check the stamped part number. If it matches 29106-08047674, you have the correct filter.
- Alternatively, use your vehicle's VIN to confirm the original equipment specification.
If you need to order, note that the same filter might be sold under different brand names (like HENGST or Mahle) with equivalent cross-references. However, sticking with the Mann brand ensures a direct match.
Installation Tips
Replacing the filter is straightforward:
- Disconnect the negative battery terminal if working near electronics.
- Remove any covers or shields obstructing the compressor.
- Unclip the old filter housing; it may twist or slide off.
- Install the new filter in the same orientation. Ensure the gasket or O-ring seats properly.
- Secure any clips and reassemble.
A common mistake is installing the filter backwards. Note the airflow direction arrow molded into the housing. Also, avoid overtightening plastic clips.
Final Recommendation
If your vehicle uses the Mann suspension air compressor filter 29106-08047674, replace it every 50,000 miles or whenever you suspect reduced compressor performance. This filter is inexpensive compared to the cost of compressor failure. While you can find aftermarket alternatives, using the genuine Mann part guarantees proper fit and filtration. Before purchasing, double-check compatibility with your specific model and year. For most BMW and Land Rover owners with air suspension, this filter will be the correct choice. Keep your suspension reliable with a simple filter swap.
