O2 Sensor Air Fuel Ratio Lambda for Audi A3 A4 A6 A8 TT

Upgrade or replace your vehicle’s oxygen sensor with this O2 Sensor Air Fuel Ratio Lambda designed for a broad range of Audi models, including A3, A4, A6, A8, and TT. This direct-fit sensor helps the engine precisely monitor exhaust oxygen levels, enabling the ECU to adjust the air–fuel mixture in real time. The result is smoother idle, better throttle response, reduced emissions, and improved fuel efficiency—especially important as the engine ages and sensor performance wanes. Built for reliability, this IWOKPHD sensor aligns with OE specifications to ensure a stable installation and accurate readings across a variety of operating conditions. Please check the product picture for fitment before ordering, and if you’re unsure, contact us before you purchase. Ordering with confidence helps avoid mismatches that can affect performance. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
