Subaru WRX 2009, Upstream OE Connector Air Fuel Ratio Sensor by Denso®, 1 Piece. The air/fuel ratio sensor sends information to the engine management computer to makes adjustments based on driving conditions. This wider range and variable adjustments controls the motor to burn fuel more efficient and produce less emissions.
Notes: Made in Japan.
- Tarnish-proof platinum electrodes provides longer life and maintains accuracy
- Quick-response planar zircon element can quickly detect oxygen concentration
- Measures A/F ratios from approximately 12:1 to 19:1
- Increased performance by mapping a/f ratios throughout rpm range
- Reduces emissions by keeping the air-fuel mixture at an optimum ratio
- Reduced fuel consumption and maximizes catalytic converter life
As the automotive industry continues to improve on their standards Denso is keeping the pace with advancements in our engineering to meet the demands from the industry. Also as light duty fleet owners are holding on to their vehicles for longer periods, Denso continues to make auto parts available for those critical replacement parts for all applications.
As oxygen sensor technology has evolved, Denso's engineers have been there every step of the way. From the first thimble-type sensors to heated, quick-response sensors required to meet ever more stringent emissions regulations, Denso has supplied the OE industry with quality components. Denso continues to innovate with the latest development in oxygen sensors, known as air/fuel sensors. These components, also known as wide-band oxygen sensors, have a broader response range to provide much finer control of air/fuel mixtures over a greater variety of operating conditions. Denso helped to develop this important new technology. Consumers can rely on Denso First Time Fit™ air/fuel sensors.102.90 106.44
