Masata BMW N55 Lambda Spacer Fooler O2 Oxygen Sensor Boss Stainless Steel (M2, M135i, M235i, 335i & 435i)

The N55 spacer is designed to move the lambda sensor after the catalytic converter away from the flow of exhaust gases when a car has a sports cat or Decat to keep the engine light off.

It can also be used in some applications to move the lambda sensor away if it’s touching something and the space is there to fit and use this.

  • Height when fitted: 45mm
  • Total height without fitting: 50mm
  • Length: 45mm
  • M18 x 1.5mm thread

We cannot guarantee this will work on every vehicle as each one can be completely different.
