    Specifications: 

    OE Numbers: 

    25383922, 25379713, 12580420

    12605109, 19420707, 12570790

    Product Material: High-quality ABS & Copper

    NOTE: Professional installation is highly recommended, installation instruction is NOT included.

     

    Features: 

    *Reliable Signal Transmission

    The wiring harness provides the necessary power for the throttle, quickly transmits control signals, and accurately controls the opening and closing of the throttle. At the same time, it feeds back the position or status of the throttle to the ECU so that you can make real-time adjustments.

    *Improved Driving Experience

    The engine's power response can be made faster and more agile by optimizing throttle control, which not only effectively improves the engine's combustion efficiency and reduces fuel consumption, but also makes the acceleration process smoother and the driving feeling more comfortable.

    *High Quality

    Made of high-quality copper wire, the surface is wrapped with ABS plastic.

    *Excellent Performance

    It can effectively reduce problems such as weak acceleration, unstable idling, sudden engine stalling, etc. caused by wire damage, and provide a long-term reliable service for your engine.

    *Regular Maintenance

    To ensure smooth throttle operation and prolong its service life, it's important to periodically check the wiring integrity of the throttle harness, clean carbon build-up, and check the plug connections to ensure that the throttle harness has a tight and reliable plug connection.

    NOTE: Professional installation is highly recommended, installation instruction is NOT included.
