MAHLE LX 3996 Air Filter for Royal Enfield Classic 350 UCE

Replace a dirty or clogged factory-style air filter with the MAHLE LX 3996, a branded replacement air-filter element catalogued by MAHLE for the Royal Enfield Classic 350. It is a strong choice for riders who want a recognised filtration brand while retaining the original air-box layout.

For part-number matching, the same MAHLE application is listed under Purolator 2277ELI99. The Royal Enfield Classic 350 parts catalogue identifies 143548/A as the corresponding OE air-filter element reference for the 350cc filter-box assembly.

OE Reference for Customer Verification

143548/A is the Royal Enfield air-filter element reference shown for the Classic 350 350cc filter-box assembly. Use this OE number as an additional fitment check when comparing the existing filter, service invoice or parts catalogue.

The OE number is provided strictly for cross-reference and identification. The product supplied under this listing is MAHLE LX 3996, not a Royal Enfield-branded genuine spare.

Why Replace the Air Filter?

• Helps trap dust and road contamination before it enters the intake system.
• Supports proper airflow through the motorcycle's original air box.
• Useful during scheduled servicing or when the existing filter is visibly dirty, damaged or excessively clogged.
• Especially relevant for motorcycles regularly ridden in dusty road conditions.

Before Ordering

Please verify all three points wherever possible:

1. Your motorcycle is the compatible Royal Enfield Classic 350 UCE generation.
2. The required filter matches MAHLE LX 3996 / Purolator 2277ELI99.
3. The OE reference used on the vehicle/application is 143548/A.

Not for Classic 350 Reborn / J-Series. The newer J-platform Classic 350 uses a different air-filter system. Do not order only on the basis of the words "Classic 350".
