AWE Tuning S-FLO intake for F22 228i (N20 engine) - not the S55-powered M2, not the F23, not the F20 125i. This is the sealed carbon airbox + turbo inlet combo that replaces the restrictive factory silencer and flimsy paper filter.
For F22 228i only - confirmed fit on N20B20A engines; not compatible with F22 M235i (N55) or F22 M240i (B58)
Stage 1 fast road & track day ready - no ECU remap needed, retains OEM MAF location, no CEL when fitted correctly
Decat-friendly intake note - sharper spool, more turbine whistle, less drone than open-filter kits
Washable S-FLO panel filter - easy access without removing airbox; no disassembly to inspect or clean
UV-stabilised 2x2 twill carbon - heat-resistant clear coat, no yellowing on UK garages or track-day heat soak
Part #170-4001 - includes airbox, turbo inlet pipe, S-FLO filter, mounting hardware, and gaskets
