Product Details

The ACDelco 12655677 is a GM Genuine Parts heated oxygen sensor (O2 sensor) designed as a factory-recommended replacement for select high-performance GM vehicles. As a genuine OE component, this sensor is manufactured to the same rigorous standards used during vehicle production and validated by General Motors for optimal quality and reliability.

This heated oxygen sensor is a critical feedback component in your vehicle's exhaust system that measures the proportion of oxygen in exhaust gases. The engine control module (ECM) uses this data to continuously adjust the air/fuel ratio to the optimal value of 14.7:1, ensuring maximum engine performance, fuel economy, and emissions control.

Key Features:

  • GM Genuine Parts OE quality for exact fit and function
  • Heated sensor design for faster response and accurate readings
  • Optimizes air/fuel ratio for improved performance and fuel economy
  • Helps maintain proper emissions control
  • Designed and tested to rigorous GM engineering standards
  • Direct replacement for original equipment
  • Backed by ACDelco 12-month/12,000-mile limited warranty

When oxygen sensors fail or provide inaccurate readings, engine performance suffers and fuel consumption increases. Replacing a worn oxygen sensor with this genuine ACDelco component restores proper engine management function and helps your vehicle run as efficiently as intended by the manufacturer.

No complaints. ordered a BAK Industries Truck Bed Cover BakFlip G2 for my Honda Ridgeline on 1/11/12. Package was shipped on 1/13/12 and arrived 1/18/12, delivered undamaged. <br><br>Autoplicity was cheaper than Amazon by about $40 (after shipping), and I didn't need to compromise on service. I would definately use them again.

Great price..easy-to-use shopping

Should offer free shipping like most other online vendors.

Please indicate where your company is located to help calculate shipping time, thanks

Easy to find parts

I just finished a transaction with this company and decided to write my very first post, based upon my experience with them. To be honest, a few short hours ago I was wary of how this would turn out. There had been a miscommunication with shipping and it started to go down hill. Lo and behold, something happened that is rare today. The company, from top to bottom put all of their efforts together, communicated with me even during a Holiday and rectified the situation. Not only would I recommend Autoplicity to others but implore potential customers to use them confidently. Their work ethics and customer service is top notch and I am very grateful for my renewed trust that there is more than just big box, fast food companies out there. Thank you again!!

Fast process

Almost a perfect score! I was pleased with the customer service but knowledge about their products warranties was lacking. Other than that, the representative that I spoke with on the phone was great. He was friendly and had a good overall knowledge of the products I was asking about. Pointed me in the right direction because I couldn't be happier with my bike rack. They had the best prices, lowest shipping costs, and my order arrived a day early. Great website to work with. I will definitely be doing business again and spreading the word about Autoplicity.com.

Thanks

Great price.

Fast shipping and good pricing, will definitely use again

Cheapest I could find ANYWHERE. Fast shipping. I will definately use them again.
