Lambda Sensors, also known as O2 or Oxygen Sensors, work together with the vehicle’s fuel injection system, Catalytic Converter and engine management system or electronic control unit (ECU) to help achieve the lowest possible output of environmentally harmful engine emissions. 

As one of the world's foremost developers and manufacturers of original vehicle parts and systems, DENSO's understanding of lambda sensor technology is unrivalled. Since they first produced them in 1977, DENSO has become one of the leading lambda sensor suppliers in the world, with several hundred million of their devices measuring the air/fuel mixture in cars worldwide. And as the automotive industry continues to improve its emission standards, DENSO's engineering advances ensure that their lambda sensors become more advanced – featuring pioneering sensor technologies that help cars to burn fuel more efficiently and produce fewer emissions.

DENSO First Time Fit® parts meet or exceed all manufacturer standards, mount properly with a minimum of installation issues, and provide years of reliable service.

SHIPPING IS FREE* for orders of £75 and over , regardless of the weight of your order.
We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £5.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
  • Priority shipping is also available.
