Product Details

The Kooks Headers CAS-109014 is a 12-inch oxygen sensor extension harness designed specifically for Ford applications. This extension harness features a 4-pin round connector configuration that provides the additional length needed when installing long tube headers or aftermarket exhaust systems that relocate O2 sensors further from the factory wiring harness position.

Key Features:

  • 12-inch extension length provides adequate reach for relocated oxygen sensors
  • 4-pin round connector design ensures proper signal transmission
  • Factory-style weatherproof connector maintains durability in harsh underhood environments
  • Plug-and-play installation with no cutting or splicing required
  • Handcrafted in the USA with quality materials and construction
  • Engineered specifically for Ford vehicle applications

This extension harness eliminates the check engine light issues and O2 sensor error codes that can occur when aftermarket headers move the oxygen sensor bungs further downstream. The proper length and OEM-quality connectors ensure reliable sensor operation and accurate air-fuel ratio monitoring. Essential for maintaining proper engine management when upgrading to Kooks long tube headers or other performance exhaust systems.

I've been through several websites looking for this tire. I was hoping to buy two but glad to see that there's at least one in stock and confirmed. So far everything is good.
