Engineered with the use of the cutting-edge sensor technology, they are a fantastic way to regulate engine performance and emissions. Since they deliver OE quality and reliability, you can be confident in their superior fit and function in your vehicle.


  • Designed to help reduce fuel consumption and harmful emissions
  • Made with the use of state-of-the-art sensor technologies
  • Corrosion-resistant stainless steel construction
  • Guaranteed to deliver OE quality and reliability
  • Proven to provide dependable service for years ahead

The emission control system of your vehicle consists of various components, including oxygen sensors, catalytic converters, throttle actuators, etc. that work together to limit the discharge of harmful gases into the atmosphere. The main purpose of the sensor is to monitor the air fuel ratio and send these data to the engine computer. If the sensor is failing, it can send incorrect information to the computer which may lead to drop in power output if the air fuel mixture is too lean or decrease in fuel efficiency if the mixture is too rich. So don’t forget to check your sensors for damages and replace them in time to ensure optimal engine operation.

With fuel prices rising and emission regulations becoming tougher and tougher, the need to know that the perfect ratio of air and fuel is maintained is more important than ever. Denso oxygen and fuel ratio sensors are a great solution to ensure optimum engine performance as well as reduce fuel consumption and emissions. Precision engineering, superior design and high OEM quality – that’s what these top-of-the-line products are recognized for. Denso sensors are manufactured utilizing superior grade materials and pioneering sensor technology to help your engine burn less fuel and produce fewer emissions. With a durable corrosion and contaminant-resistant stainless steel housing and double protection cover, these products are guaranteed to serve you for many years to come. Superior in every way, they are proven to deliver flawless first-time fit along with unrivaled performance.
