Found another advert ..................... All listings are in complete compliance with eBay's duplicate listings policy. We have no more than 10 listings, which use identical resistance values. Each one of the modifications use a precise and distinctive resistance value listed below based on the electrical system of the specific vehicle. These various values range from 100 up to 9,500 ohms This modification for the VW GTI has a resistance value of 6,200 ohms to dominate the sensor and signal the computer that the engine is receiving air at the temperature of 36 degrees. This auction is for an Intake Sensor Modification Resistor. This modification resistor will give you very similar results that an ECU (Electronic Control Unit) upgrade chip will do. This modification connects to your intake sensor. It works by fooling your ECU into thinking that the air coming into the intake is colder therefore causing it to advance the timing and letting out the fuel supply creating more horsepower. This is a resistor that will modify your Air/Fuel ratio and slightly change your engine timing to run stronger and with increased power. This Intake Sensor Modification Resistor will fit just about all models and make of cars and trucks from 1987 and newer that are fuel injected (non Turbo). Its extremely easy to install no tools are required and this modification resistor will not damage your vehicle in anyway!!! This only takes about 10 minutes to install.
