POCYBER Ignition Coil Set (6 Pack) — BMW N46/N52/N53/N54/N55

Construction centers on high-conductivity copper windings paired with high-dielectric performance epoxy, a combination that maximizes voltage transfer while protecting the internal components from heat and vibration. These aren't generic universal coils — they're engineered specifically for BMW's N46, N52, N53, N54, and N55 engine families, covering a broad range of E and F chassis models from the E46 M3 and E90 335i to the F10 550i, X5, and beyond. Cross-reference compatibility using OE part numbers 0221504470, 12138616153, 12138657273, 12137594937, 12137562744, or 12137571643 to confirm your fitment before ordering.

Installation is straightforward — each coil drops directly into the stock location with no modification required. Replacing all six at once is the recommended approach, since coils on these engines tend to degrade at similar rates, and mixing new units with worn ones can leave underlying misfire issues unresolved. Every coil in the set is individually inspected and tested prior to shipment, and the complete kit is covered by an 18-month warranty, giving you confidence in the investment well past break-in.
