BMW E81 E87 120i BMC Panel Air Filter - Part Number 123456

For the E81 and E87 120i (N43B20, 2004-2012) - not the 116i, 118i or 125i - this is the genuine BMC panel filter, part number 123456. It’s a direct-fit replacement for the standard paper element in the stock airbox. No mods. No trimming. Just better breathing.

• Stage 1 fast road essential: improves airflow without triggering CELs or upsetting MAF calibration
• Fits E81 hatchback and E87 coupe with N43B20 engine only - not N45/N46/N52/N54
• Cotton gauze media, pre-oiled, washable and reusable - ideal for daily driver or track day use
• Red thermoplastic frame seals cleanly into OEM airbox; no leaks, no rattles, no ‘induction roar’ unless you’re on full throttle
• Search terms covered: BMC E87 air filter, E81 120i panel filter, N43B20 air filter, fast road air filter BMW 1 Series, reusable panel filter E81/E87
