Big Gun TFI Power Box Honda Pioneer 700 / 700-4

Any aftermarket exhaust allows an increased amount of airflow through your engine by reducing restriction. Big Gun offers this plug-and-play TFI Power Box fuel controller to correctly tune your machine after installing one of their exhausts, adding more fuel to maintain good ratios throughout the rpm range. Protecting your engine from running lean helps keep temperatures down and helps maintain smooth stock-like drivability. Integrated faceplate buttons allow for easy adjustments without the use of an external device.

  • Plug-and-play harnesses plug directly in line with your stock fuel injector harnesses using factory-style terminals
  • No extra computer, phone or tablet required to make adjustments
