NGK 2020 Toyota Highlander OE Type 4-Wire A/F Sensor

If your 2020 Toyota Highlander is showing a check engine light or you're noticing a drop in fuel economy, a faulty Air/Fuel Ratio (A/F) sensor could be the culprit. This NGK A/F sensor is built to match the original equipment specifications, ensuring it works seamlessly with your vehicle's computer to monitor the air-fuel mixture. Getting this right is key for efficient combustion and keeping emissions in check.

NGK is a well-known name in ignition and sensor technology, and this sensor is made to be a direct replacement for your factory unit. It's a 4-wire sensor, which is typical for A/F sensors that provide both upstream oxygen readings and heater circuit control. Installing a new A/F sensor like this one can help restore your engine's performance and fuel efficiency, making sure your Highlander runs as smoothly as it should.
