OEM Oxygen Sensor for Blacktop/ Silvertop 20V 4AGE Engines
Share this part with a friend in need!
This OEM O2 Sensor is a direct replacement for your stock 20V one. Replacing your Oxygen sensor can improve fuel economy, performance, and overall engine health.
Getting an accurate reading of exhaust gas contents helps the ECU decide how much air and fuel to allow into the engine. Over time, sensors may fail or read inaccurately, so it is important to keep these sensors updated!
For people running a 20V swap in their AE86 with a stock blacktop/ silvertop ECU, it is important to have the correct Oxygen sensor or the vehicle will run improperly. This is the correct O2 sensor for these stock ECU setups!
