aFe Power 16.8L SISU Tier IV Engines AG Diesel Solutions Performance Module SISU1684

The Ag Diesel Solutions SISU1684 Performance Module is designed for 16.8L Tier IV SISU engines. It increases horsepower, torque, and fuel efficiency. The module is engineered, designed, and manufactured in the USA and comes with US-based customer service.

This module intercepts and modifies factory ECM signals en route to fueling systems, providing performance benefits without communicating directly with the ECM. This plug-and-play installation leaves no footprint in the ECM, helping to maintain the vehicle's factory warranty, provided the module is removed before service.

The SISU1684 offers multiple power levels that can be changed on-the-fly. It includes installation instructions with photos and comes with a 3-year manufacturer warranty.
