When installing aftermarket cold air intake in your vehicle, the inlet air temperature (air temp sensor / intake temp sensor) sensor is frequently relocated, usually far enough away from the original wiring location that the connector cant be re-installed. You cannot cut and splice oxygen sensor wiring since this can permanently damage the sensor and considerably reduce accuracy of the signal. These extensions are "Plug-And-Play" and utilize OEM connectors, terminals and seals with OEM wiring to maintain precisely accurate signals and safely extend the wiring connections. Note: Please check your connector shape and color to see if it matches your application.
