Product Details

The APW Warehouse Supplies AP4-91 is an OE-style replacement oxygen sensor designed to restore proper engine performance and fuel efficiency. This sensor monitors the oxygen content in exhaust gases and sends critical data to the engine control module to maintain optimal air-fuel ratios.

Key Features:

  • Direct OE-style replacement for reliable fit and function
  • Precision-engineered sensing element for accurate readings
  • Durable construction designed to withstand harsh exhaust temperatures
  • Helps maintain fuel efficiency and reduce emissions
  • Restores engine performance and eliminates check engine light codes

Oxygen sensors play a vital role in modern engine management systems by continuously monitoring exhaust gases. A faulty oxygen sensor can lead to decreased fuel economy, rough idle, increased emissions, and reduced engine performance. The AP4-91 provides a cost-effective solution to restore your vehicle's operation to factory specifications.

Great products, and pricing

I found a item at Autoplicity that I could not locate on other sites. The item was shipped quickly and I was advised of this by an email detailing all of the shipping information. I am well pleased with all aspects of this transaction.

Great experience! !!!

Awesome price on a B&W Gooseneck Hitch for my 2008 F-450 King Ranch

Received Monroe MA770 air shock, fit just wonderful and the installation was easy.

right parts, right price

Quick order processing. Excellent customer service when calling to inquire the status of the order.

I ordered a Rhino stainless steel exhaust tip for my 2009 Chev Silverado from Autopicity. It took approximately 1 week from when I placed my order until I received it. It arrived in excellant shape and was exactly as indicated. The part was very good quality and easy to install. It took me approximately 15 minutes to install, partly because I wanted to make sure of the appearance and location. I was very pleased with the service I received from Autoplicity and would definitely order again from Autoplicity.
