Q:Is this an upstream or downstream O2 sensors? I need 2 upstream O2 sensors. Show Less

A:BEST ANSWERHi Leo, I am pleased to assist you. This is classified as an upstream O2 sensor. Upstream O2 sensors are located before the catalytic converter. Upstream sensors monitor the air-fuel ratio and help adjust the fuel mixture for optimal engine performance and emissions control. If your vehicle information matches this product, you can use the link below to order while the part is in stock. Your order will come with a 30-day post-purchase price match guarantee.
