Product Details

The Kooks Headers CAS-109677-8 is an 8-inch front oxygen sensor extension harness designed specifically for 2018 and newer Ford Mustang applications. This essential wiring component features a 5-pin connector configuration that allows proper O2 sensor connection when installing aftermarket headers or exhaust systems that relocate the oxygen sensor mounting position.

Key Features:

  • 8-inch extension length provides proper reach for relocated O2 sensor ports
  • 5-pin connector design ensures proper signal transmission
  • Front oxygen sensor application for 2018+ Ford Mustang models
  • Manufactured in the USA from high-quality materials
  • Plug-and-play installation with OEM-style connectors
  • Backed by Kooks limited lifetime warranty to original purchaser

This extension harness eliminates the need to splice or modify factory wiring when installing Kooks headers or other aftermarket exhaust components. The proper extension length ensures a secure, tension-free connection while maintaining accurate oxygen sensor readings for optimal engine performance and emissions compliance.

Excellent

Did not receive order confirmation or shipment notification. Called customer service. They suggested looking in my email spam folder. Both emails were there. Everyone else was out of stock on my item. You guys had it and shipped very quickly. Thanks!

Good price on an item I needed

The box came beatup and 2 big holes in it..but exhaust was un harmed. Not their fault since they had it shipped from another vendor.

Fast and easy. They reference part number to manufacturer.

Gg

I found good quality product more cheaper here. I installed the shocks. Did not have any problem.
