Product reviews for NGK 21543 NTK Oxygen Sensor - Heated 4-Wire Narrow-Band O2 Sensor

Perfect transaction. Perfectly satisfied. Best price anywhere, same-day shipping. Couldn't be happier. Thanks Autoplicity.

Best prices, fast shipping, good service. Thank you!

Was looking online for the best price on a part and found that autoplicity had the lowest price and free shipping on it. I ordered it and it was shipped the next day along with tracking number. I will be ordering a few more parts from autoplicity. Order Number: 27769

The cheapest price on the net and very fast shipping.  I received my items in 3 days and they were delivered on a Saturday to make things even better.  <br><br>Will be using these guys again real soon.

I have placed orders with Autoplicity 3 times in the last 2 months, and have received excellent delivery, pricing and customer service in every instance. Thanks!

I ordered a Flowmaster cat back system for my 2012 F-150.  The order arrived the day they said it would and the product came at a fair price.  Well done.

** Update 4/18/2012<br>Everything arrived in several different shipments. I did experience a problem with some FelPro Headbolts that I had ordered. I ordered two and only received one, but after a short phone call with Paul from shipping, the problem was fixed and my second set of bolts were shipped.<br><br>They had the cheapest price that I could find on several products. I did not like the order confirmations on there website as I had to copy and paste to search for my tracking number. I am supposed to receive my order today and I am scared because the two weights do not match up. Autoplicity says 37.7 pounds and fedex says 3.8 pounds. Maybe there is more than one tracking number and I just do not know.
