Denso air/fuel ratio sensors (A/F sensors) were developed to measure air-to-fuel ratios under a wider range of driving conditions than oxygen sensors. A/F sensors, also known as wide-band oxygen sensors, send information to the engine management computer to make adjustments based on driving conditions. Their wider range and variable adjustments allow engines to burn fuel more efficiently and produce fewer emissions.

As A/F sensor technology has evolved, Denso has been there every step of the way. From the first thimble-type sensors to today's heated, quick-response sensors required to meet ever more stringent emissions regulations, Denso has supplied OEMs with quality components and continues to innovate. Denso helped to develop this important technology and you can rely on Denso First Time Fit A/F sensors.

Features and benefits of Denso air/fuel ratio sensors include:

* Tarnish-proof platinum electrode provides longer life and maintains accuracy
* Quick-response planar zirconia element quickly detects oxygen concentration
* Measures air/fuel ratios from approximately 12:1 to 19:1
* Increased performance by mapping air/fuel ratios throughout the RPM range
* Lower emissions by optimizing the air/fuel mixture
* Reduces fuel consumption and maximizes catalytic converter life
* First Time Fit design delivers the right part the first time
