Product Details

The APW Warehouse Supplies AP4-256 is an aftermarket replacement oxygen sensor designed to restore proper air/fuel mixture feedback to your vehicle's engine management system. Oxygen sensors play a critical role in monitoring exhaust gas composition, allowing the ECU to continuously adjust fuel delivery for optimal combustion efficiency, reduced emissions, and fuel economy.

Key Features:

  • Direct-fit aftermarket replacement for OE oxygen sensor applications
  • Monitors exhaust oxygen content to optimize air/fuel ratio
  • Helps maintain proper fuel economy and reduce harmful emissions
  • Designed to meet or exceed original equipment performance standards
  • Threaded fitting for straightforward installation with standard O2 sensor tools

Replacing a faulty oxygen sensor can resolve common symptoms such as a lit Check Engine light (OBD-II codes P0130–P0167 range), decreased fuel efficiency, rough idle, and failed emissions tests. The AP4-256 is offered as a cost-effective alternative to OEM sensors for compatible applications.

First package arrived late, pre-opened and appeared preinstalled. Customer service was great with shipping refund, return and re-order. Second package arrived early, new and unopened. Now ordered more products-very happy with Autoplicity!

Easy product shopping, items are tracked and shipped relatively quick, but there is little product identification and proper installation for large orders. Small pieces of paper in different languages and blurry photos of step by step fitting do not suffice.

Very good service, thank you.

Fast service and easy check out!

So far, it's been easy to place the order.

quick and easy checkout
