I am selling it because I have no chance to use it after purchasing it new. *Since this is a new and unused item, operation has not been confirmed. Please install at your own risk. Booster Plug is a product that solves these problems and improves drive performance by making the injection fuel richer by simply setting it between the intake air temperature sensor and the injection ECU. When you install Booster Plug, you can expect the following effects. ｜ The response when opening and closing the throttle is improved more smoothly ｜ Torque in the low rotation range is improved (by improving the torque, the practical rotation range is lowered and fuel efficiency can be expected to improve) ｜ Knocking, pounding, etc. at low speeds are improved ｜ Idling becomes stable ｜ Reduces afterfire that tends to occur on vehicles equipped with non-genuine mufflers. *The effects listed vary depending on the condition and conditions of the vehicle.
