Are these extensions vehicle-specific?

Yes, these Kooks CAS-104110 O2 sensor extensions are specifically designed for 2009 and newer RAM 1500 models equipped with the 5.7L HEMI engine. They may not be compatible with other vehicles or engine types.

What is the purpose of an O2 sensor extension?

When installing aftermarket headers, the O2 sensor bungs may be relocated further from the factory sensor location. An extension harness allows you to connect the factory O2 sensor to the relocated bung without cutting or splicing wires.

Are these extensions sold individually or as a pair?

These Kooks O2 sensor extensions are sold as a pair, so you'll receive two 6" extension harnesses with 4-pin connectors.
