FAQs
How often should I change the E1004L filter?
It is generally recommended to replace the filter every 15,000 to 30,000 miles, or more frequently if you drive in dusty or urban environments.
Can I clean this filter with an air compressor?
No. Compressed air can tear the filter media, allowing unfiltered air and debris to enter your engine.
Is this filter compatible with the N57 engine?
No, this filter is specifically designed for the N47 D20 and N47D20A engine codes.
Does it matter which way the filter is inserted?
Yes, ensure the filter orientation matches the flow markings on the housing, usually with the pleated side facing the intake.
What are the exact dimensions?
The filter is 300mm long, 82mm wide, and 68mm high.
Troubleshooting
Engine feels sluggish after installation
Ensure the filter is seated correctly and that no air intake hoses were left disconnected during the process.
Housing lid won't close properly
Verify the filter is pushed all the way down into the housing and that the gasket is not pinched or folded.
Pros and Cons

Setup, Compatibility & Care
To install the E1004L, locate the air filter housing within the engine bay, typically secured by clips or screws. Open the housing, remove the old filter, and carefully vacuum any loose debris from the housing tray before inserting the new Hengst filter. Ensure the rubber gasket sits flush against the housing edges to create an airtight seal.
Compatibility: This filter is designed for specific BMW models in the 1 Series, 3 Series, and X1 lines equipped with the N47 D20 or N47D20A engine. Always double-check your vehicle's VIN or engine code to verify fitment.
Care: The E1004L is a single-use paper-based filter. Do not attempt to wash or blow it out with compressed air, as this can damage the filter media fibers and compromise its filtration integrity.
