NGK 2016-13 Scion FR-S OE Type 4-Wire A/F Sensor

This NGK 4-wire Air/Fuel Ratio (A/F) sensor is built with a durable platinum-tipped element, a design that helps ensure accurate readings for your vehicle's exhaust gases. It's a direct replacement for the original sensor, meaning it's made to fit right and function like the factory part. This sensor plays a crucial role in your engine's performance and fuel economy by providing real-time data to the engine control module (ECM) about the air-fuel mixture. When this sensor is working correctly, your engine can adjust the mixture for optimal combustion, leading to better gas mileage and smoother operation.

NGK is a well-known name in ignition and sensor technology, and this A/F sensor is a solid option for many Subaru, Toyota, and Scion vehicles. It's designed to handle the harsh environment of the exhaust system while maintaining precise measurements over time. Replacing a faulty A/F sensor can resolve issues like poor fuel economy, rough idling, and check engine lights related to your air-fuel mixture. This part is a direct fit for a wide range of vehicles, including the Scion FR-S, Subaru BRZ, and Toyota 86, among many others.
