Product Details

The Kooks EX685-Z O2 Extension Kit is specifically designed to extend the reach of your oxygen sensor harness for proper fitment when upgrading to aftermarket exhaust systems on 2014-2019 Chevrolet Corvette C7 models. This complete kit includes one 16-inch rear extension harness (4-pin) and one 21-inch rear extension harness (4-pin), providing the necessary length to properly connect oxygen sensors after header installation.

Key Features:

  • Constructed with high-quality, durable wiring and OEM-style connectors for reliable connection without signal interference
  • Built to withstand high-temperature conditions commonly found in exhaust systems
  • Simple plug-and-play design, eliminating the need for cutting or splicing wires
  • Manufactured in the USA with Kooks' legendary quality standards
  • 4-pin connector configuration for direct OEM replacement fitment

Oxygen sensor extension harnesses are included in Kooks header kits where needed. This part number should only be ordered as a replacement for damaged or lost oxygen sensor extensions. The kit ensures accurate sensor readings to help maintain optimal engine performance and efficiency after installing aftermarket headers or exhaust components.

Autoplicity had the best price I could find on an Invidia downpipe for my 08+ Subaru STI. I had to pay for shipping but the total price was still well below their competitors who advertised free shipping.<br><br>Thanks Autoplicity!<br>Matt

So far so good

Extremely Impressed! I put my order in on a Thursday afternoon, and my Borgeson steering box, and steering shaft showed up on a Saturday! You cant asked for anything more, lowest price on the net, and blazing fast shipping!

Very good product, the green caliper paint is great.

So far so good. Quick, easy. Live the amazon option

This was my first order with Autoplicity and I am very happy. They had the lowest price on-line that I found. Communication was great and shipping was very fast. I ordered late on Thursday and it was at my house the following Tuesday, and I didn't pay for rush shipping. I got exactly what I expected. Will do business with these guys again.

Great price on the net among other competitors.

First time buyer from Autoplicity and found the website easy to navigate and find what I wanted quickly. They had the best price of all the other sites I checked, including shipping.
