Fitting and support

Professional installation recommended. For fitting, choose MJ Modifications in Warwickshire. Request a quote at info@mjmodifications.co.uk. We can also confirm suitability using your UK registration or last 7 of VIN prior to dispatch.

When to replace your lambda probe

  • Rough idle, flat spots or hesitation under load
  • Higher fuel consumption or sooty tailpipe
  • Emissions test problems or a persistent warning light related to mixture control

Replacing a degraded sensor restores precise air fuel feedback to the ECU, helping the engine run cleanly and efficiently.
