Ensuring consistent fuel supply and a high-intensity spark is mandatory when extracting extra performance from the highly boosted 4.0-litre V8 engine. Upgrade your fueling capacity to support massive air volume using high-flow Bosch Fuel Injectors. For owners seeking a substantial, plug-and-play power increase without permanently overwriting their complex factory ECU software, we highly recommend our RaceChip GTS5 Black Tuning Boxes. These advanced modules safely intercept and optimize sensor data to deliver massive, immediate gains in both horsepower and torque across the entire rev range.
