Racing Suction

Racing Suction

Code No. 70020-AF104



  • Optimization of the pipe design reduces bends where possible and intake air flow resistance is minimized.
  • Increased response in the higher rev range unleashes the original potential of the engine.
  • Eliminates light detonation/knocking which the stock car is prone to. A safety margin has been worked into the design for peace of mind.






  • The Racing Suction Reloaded is air cleaner for engine. Please change the Super Power Flow filter regularly for the best result.
  • Please change for the heat resistant type Spark spark plug because you will have more engine output with this item installation. Especially for higher power sport racing you must change it!
  • This item is produced from the stock vehicle, but you might need to reset for adjustment of the air flow meter output device or fuel related devices (such as F-CON) because there are many different types of vehicles.
