BMW E90 E92 E93 M3 N54 N55 crankshaft position sensor NGK 81331

Direct-fit NGK crankshaft position sensor for BMWs with N54 and N55 engines - including E90, E92 and E93 M3s. No coding, no adapters, just plug-and-play reliability.

Fixes P0335/P0336 faults, rough idle, hard starting and intermittent stalling. Built to OE tolerances but with tighter signal stability than many OEM units.

• NGK part number: 81331 (also marked CHN3-V332)
• Fits N54 and N55 only - not compatible with N20, B58 or older M54/N52
• Proven on fast-road and track-day builds where timing integrity matters
• No software reset needed post-fitment
