Plug And Play. When modifying your RAM's exhaust system, the factory oxygen sensor wiring harnesses usually come up short and won't reach the O2 sensors. However, a set of 18" and 6" Kooks harness extenders will help bridge the gap allowing you to reconnect your sensors in an easy plug-n-play fashion.

Superior Quality. Longer than stock, this Kooks Extension harness is manufactured from quality automotive grade wire with a high temperature covering for extra protection and features factory correct connectors and terminals for an easy trouble-free installation.

Warranty. The Kooks O2 Sensor Extension Harnesses have a limited lifetime warranty from the manufacturer. This warranty covers against any defects in the manufacturing process and material and structural faults, and it is not transferable.

Not CARB Certified. This C&L Racer Cold Air Intake is not CARB certified at this time, therefore it is not legal for use in California or other states adopting California emission standards. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

Application. This Kooks O2 Sensor Extension Harness Kit is designed for use on 2004-2008 Dodge RAM 1500 models equipped with the 5.7L V8 engine. Sold as a set of four.

Please Note. O2 Sensors are not included with this Extension Kit.

          Did the trick.

          Didn't want to cut wires so got extensions instead. These worked great.
