aFe Pedal 2 Metal Throttle Enhancer improves your overall driving enjoyment. Most newer vehicles are manufactured with Electronic Throttle Control. This means that your acceleration is no longer powered with a throttle cable that gave you a linear relationship between your foot and the throttle body. Everything is now powered by electronics and your vehicle's computer. The electronic throttle does not provide the same performance since it creates a lag from your initial accelerator push. The largest disadvantage is that the throttle response time is significantly slower. aFe Pedal 2 Metal Throttle Enhancer connects to the OE connector behind the accelerator pedal and uses Bluetooth technology to control your throttle response from a smartphone app. This gives you the ability to eliminate the delay from your accelerator, allowing your engine to respond faster. As a result, your gas pedal becomes more sensitive for a sportier or old school feel. | aFe Pedal 2 Metal Throttle Enhancer 77-20001
