It removes carbon sludge without damaging the ISC servo or removing the molybdenum coating on the butterfly valve. This throttle valve cleaner is volatile and has improved insulation properties, making it suitable for use in injection-fueled vehicles. If you're experiencing poor fuel economy or engine starting problems, give it a try! ●1 bottle (180ml) *Please read carefully* This product's container is made of a thin material, so there may be scratches, dirt, or dents on the exterior at the time of delivery.
