Product Details

The APW Warehouse Supplies AP4-1 is a direct-fit replacement oxygen sensor designed to restore proper exhaust gas monitoring and fuel management to compatible vehicles. The oxygen sensor (also called an O2 sensor or lambda sensor) plays a critical role in the engine management system by measuring the oxygen content in exhaust gases and relaying that data to the engine control module (ECM).

A failed or degraded oxygen sensor can result in poor fuel economy, increased emissions, rough idling, and illuminated check engine lights. Replacing a worn sensor with a quality unit like the AP4-1 helps restore optimal air/fuel ratio control and catalytic converter performance.

Key Features:

  • Direct replacement for OE oxygen sensor applications
  • Helps restore proper closed-loop fuel control
  • Supports accurate air/fuel ratio monitoring by the ECM
  • Compatible with upstream (pre-cat) and/or downstream (post-cat) sensor positions depending on application
  • Designed to meet original equipment performance standards

Always verify fitment using the vehicle's year, make, model, and engine specifications before installation. Refer to your vehicle's service manual for proper torque specifications and installation procedures.

Fast shipping Thanks.

Great!

Easy to Navigate and great prices

Nice website

Easy to navigate, fast shipping and able to get parts that are practically discontinued. Great experience.

So far so good.

Great prices and fast shipping. Will use this company many more times in the future.

Ordered an EGR bug shield. After a short delay due to the Christmas holiday I called and customer service quickly tracked it down and it showed up a few days later. Best price on the internet!

Had a little trouble finding the item needed. A search option would be helpful.

Shopped for the best price I could find on my combo pintle/tow hitch and Autoplicity came in the lowest. So I'm expecting maybe a super long delivery right? Nope they shipped it Immediately and I just got it like 3 days later. I will order again in a heartbeat. Have no fear their a great supplier

Very good experiance with seller. I order husky floor liners for my '09 honda accord and they where 30-40% less than any other online store. Item arrive quickly, And couldn't be more happier with transaction. Defenetly i will look forward for my next car needs to deal with Autoplicity. 5 Star defenetly...............

Super low prices even for an internet company! Items are hard to find on their website but once you do the price is way better than anywhere else. If they improved the functionality of their website they would take over the world!

This was my first time placing an order with Autoplicity and I would not hesitate to order from them again. The product was as described and shipping was very fast, received the item in 2 days. Good price too! Thanks Autoplicity.
