The N43-era four-cylinder petrol BMWs are honest, high-volume cars, and this compact 160mm x 140mm panel is their washable airbox element. Ramair's dual-layer foam drops into the factory airbox on the 116i, 316i, 320i and X1 sDrive18i applications in the table - UK-made and reusable, fitted in the time it takes to unclip the lid.
The 116i and 316i N43 rows carry several overlapping year spans from the source data - every listed span is covered, so match chassis code, engine and year and check the part number if your car sits at a boundary. Ramair's RPF-1233 covers the N45N-engined cars instead.

N43 is the direct-injection four-cylinder in later E8x/E9x 116i and 316i cars - check your engine code or registration against the table, and see Ramair's RPF-1233 if yours is the N45N.
The source fitment data lists several overlapping spans; all of them are covered by this panel. Match your exact year and confirm the part number if in doubt.
Wash and refit with Ramair's CK-003 cleaning kit, sold separately - the element itself stays in service.
Model year, engine, drivetrain, hardware and existing modifications can all change what fits. Check the applications and supplier notes above, or send us your exact vehicle and setup before ordering.
