Bosch a global supplier to automakers manufactures an OE-equivalent direct fit air fuel ratio sensor that maintains the quality and performance of the Original Equipment it replaces. Bosch Wideband Air/Fuel ratio sensors utilize a more sophisticated sensing element that enables them to produce a precise output in proportion to the air/fuel ratio. As a result, a wideband A/F sensor measures exhaust gas oxygen accurately from as rich as 9.0:1 to as lean as free air. The use of the Wideband A/F sensors is growing rapidly as original equipment in vehicles and in high-performance specialty markets.

Product Features:

• Tarnish-proof platinum electrodes
• Base ceramic probe of Zirconium and Yttrium
• Patented Platinum Power Grid
• Fine particle filter Installation Notes: Vehicles equipped with Air Fuel Ratio Sensors may look very similar to the Oxygen Sensor. Please confirm the correct part before ordering and if the connector does not match, do not install.
• Patented Platinum Power Grid.

NTK is the world’s largest supplier and manufacturer of OEM oxygen sensors. Oxygen sensors play a critical role as part of the vehicle’s on-board diagnostic system in maintaining optimal engine performance, maximizing fuel efficiency and reducing harmful emissions. While conventional switching oxygen sensors only switch rich or lean, wideband oxygen (or Air-Fuel Ratio) sensors produce a linear output signal that allows the ECU determine exactly how rich or lean an engine is running and make continuous and precise adjustments of the air-fuel mixture to stay closest to stoichiometric, providing the best possible combustion and fewest emissions. A ceramics company at our core, NTK uses state-of-the art technology enabling complete control of the ceramics used in our wideband oxygen sensors from raw material to finished product. Trust The Sensor Specialist for full-line market support and OE application technology.

Rein Automotive OE temperature sensors are made to factory specifications ensuring proper fit, form and function. The temperature sensor is used to report exhaust temperatures to the vehicle’s ECU. The vehicle uses this information to control engine and emission paramaters. Rein temperature sensors include a vehicle specific connector that fits directly into the factory plug. Our quality temperature sensors aim to provide the professional repair technician and vehicle owner the peace of mind and trust that is expected from an OE component.

Product Features:

• Direct OE replacement
• Designed to meet or exceed factory specifications
• Made using high quality materials
• Uses vehicle specific style connector for quick replacement.
