FAQ
What is the Kooks CAS-104110?The Kooks CAS-104110 is a set of two 6-inch O2 sensor extension harnesses designed for 2009-2015 Ram 1500 trucks with the 5.7L HEMI engine. It restores proper O2 sensor connection after long tube header installation.
Why do I need the CAS-104110 after installing headers?Long tube headers relocate the O2 sensor bungs, which can leave the factory harness too short to reach. The CAS-104110 adds the length needed to reconnect the sensors properly.
Which vehicles fit the Kooks CAS-104110?The CAS-104110 is designed for 2009-2015 Ram 1500 trucks equipped with the 5.7L HEMI V8.
Is the CAS-104110 a plug and play harness?Yes, it uses factory style 4-pin connectors so no wire splicing or cutting is required.
How many extensions come in the CAS-104110 kit?The kit includes two 6-inch extension harnesses, one for each rear O2 sensor location.
Will the CAS-104110 cause a check engine light?No, the extension is designed to maintain proper sensor signal integrity and prevent codes caused by an improperly seated or strained connector.
Do I need the CAS-104110 with every Kooks header kit?It depends on your specific header configuration; the CAS-104110 is intended for installations where the factory harness does not reach the relocated sensor bung.
Can the CAS-104110 be used with non-Kooks headers?While designed to pair with Kooks header kits, the CAS-104110 can work with any header setup using the same factory-style 4-pin O2 sensor connector.
