Product Details

The APW Warehouse Supplies AP4-390 is a direct-fit oxygen sensor designed to monitor exhaust gas oxygen content and provide critical feedback to your vehicle's engine control module. This sensor helps optimize fuel efficiency, reduce emissions, and maintain proper engine performance by continuously measuring the air-fuel ratio in the exhaust stream.

Key Features:

  • Direct replacement oxygen sensor for OE specifications
  • Precision-engineered sensing element for accurate readings
  • Heat-resistant construction designed for harsh exhaust environments
  • Helps maintain optimal fuel economy and reduce harmful emissions
  • Vehicle-specific design ensures proper fit and function

Oxygen sensors are critical emission control components that degrade over time due to exposure to extreme heat and combustion byproducts. A failing oxygen sensor can trigger check engine lights, decrease fuel economy, and increase emissions. The APW AP4-390 provides reliable performance to restore proper engine management system operation.

I ordered an exhaust setup (headers and a cat-back) late monday night, an it was shipped on wednesday. Thanks for a fast transaction Autoplicity!

so far so good

Happy

I had a hard time finding this part, but lucky this website had it. Everything was fast and easy, with no hassle. Thank you

Best Price I could find on this item

Good Job

Thanks! glad you had the parts!

Great Parts.Great Service.Thank you.

I ordered the Truxport tonneau cover for my Nissan Frontier. I am very happy with Autoplicity,they have the best price by far on this product,and they promptly sent me an email when it was shipped.....the ONLY thing I wish they would have done but didn't is to include a tracking number. I think the reason they didn't include it is that it was shipped directly from the manufacturer,but they did give me the tracking number when I called and asked for it. Overall a very positive experience

By far they had the cheapest prices. I made a mistake on my order and they were able to switch it out for the correct item before it shipped. Amazing guest service over the phone, will def shop again with their low prices.
