Description
To get the most efficient shape for tuning engines(400 to 600ps), the diameter & length of the intake pipe and the shape of the intake collector's cross section were redesigned.
This improved air distribution to each tube as well as equalizing the air flow volume to each side, which increased torque in the mid-speed range.
Fuller air intake to both the front and rear reduces the difference in air temperature on both sides of the turbine.
This optimizes the air-fuel ratio and ignition timeing, which increases output and improves fuel consumption.
Product Specifications:
- Collector volume: 4.1 liter (genuine = 3.4 liter)
- Intake pipe length: 73.8mm (genuine = 48.5mm)
- Intake pipe diameter: tapered from ø 43 to ø 45 (genuine = ø 45)
- Material, production method: cast aluminum
Product Note:
- This product cannot be installed with the engine mounted.
- Installation of this product will change the characteristics of the engine, necessitating adjustment of the engine control unit. Failure to do so very likely will result in damage to the engine.
- The engine improvement figures shown above are based on internal company testing. The actual level of improvement will depend on the engine specifications, conditions of air-fuel mixture and ignition timing, weather and the precision of measurement.
- This product cannot be used with single, large-diameter throttle chambers
