Michigan Motorsports TPI TBI 3-Wire Heated Oxygen O2 Sensor Wire Harness Adapter - Fits IROC - 48" Lead - Compatible with AFS74

• Enhanced Sensor Performance: Facilitates the upgrade from a single-wire to a 3-wire heated O2 sensor, ensuring the sensor reaches optimal operating temperature quickly, especially beneficial when using aftermarket headers that lower exhaust gas temperatures.
• Extended Lead Length: Features a 48-inch lead, providing flexibility in routing and installation, accommodating various vehicle configurations and ensuring a secure and tidy setup.
• Easy Installation: Designed for straightforward installation: connect to the OEM O2 sensor lead, wire the red lead to a "RUN" switched source, ground the black wire, and plug in the heated O2 sensor, minimizing installation time and effort.
• Compatibility: Compatible with ACDelco AFS74 sensors or equivalent, ensuring broad applicability across various vehicle models and making it a versatile choice for upgrades or replacements.
• Improved Engine Efficiency: By enabling the use of a heated O2 sensor, this adapter contributes to more accurate air-fuel ratio readings, leading to improved engine performance, fuel efficiency, and reduced emissions.

Allows install of 3 wire heated O2 sensor on cars that came with 1 wires sensors. This will allow proper operation operation with headers which lower exhaust gas temps and may not allow o2 sensor to get up to operating temperature. Just plug in the OEM O2 sensor lead and wire the red lead to a "RUN" switched lead and ground the black wire and you are ready to plug in the AFS74 or equivalent . Very easy install.
