To find the most suitable shape for tuning engines (400ps to 600ps), the diameter and the length of the intake pipe, and the cross section shape of the intake collector was redesigned. The distribution of air to each tube was improved to provide more equal airflow volume, improving torque in the mid-speed range. Improved air intake volume between pipes of the front and rear sides
reduces the difference in air intake temperature on both sides of the turbine, optimizing the air-fuel ratio and ignition timing, and providing increased output and better fuel consumption. Simple bolt-on installation means that no additional work is required (however, the throttle linkage and throttle sensor must be adjusted).

• Intake temperature difference at the entrance of turbochargers is improved on average 18% in the 2400 to 7600 rpm range.
• At 4800 to 7600 rpm, power output is increased by an average of 1.8%, while fuel economy is improved on average by 0.4%.
