Product Details

Fuel Injection Throttle Body by Hitachi®. Precise airflow control, accurate engine control, and extended service life is what you'll get with this premium electronic throttle body by Hitachi. It features a microcomputer to control the valve opening quickly and precisely, keeping the engine torque at a constant level when adjusting the air/fuel ratio and thus providing improved fuel economy and emissions performance.



  • Compact, lightweight DC motor ensures easy mounting in various engines
  • Features a multiple-output throttle sensor for a more accurate signal output
  • Equipped with a non-contact position sensor for maximum durability
  • Precise valve opening maintains stable performance at a wide range of environmental conditions
  • Tested to original equipment performance specifications

The electronic throttle body (ETB) is a main part of an electronic throttle control (ETC) system. The ETB controls the volume of air flow entering the engine. It features a butterfly valve which opens and closes according to a signal from the engine control unit. With an electronic control throttle body, it is possible to open or close the throttle valve according to the changing condition of the vehicle. Compared to a mechanical type throttle body, it is a system of higher accuracy that allows for increased fuel economy.

If your idle speed is reduced, your engine stalls when warmed up, restarted, or during acceleration, chances are you have a malfunctioning throttle body. Get a top-grade ETB from a trusted, world class quality leader and an original equipment manufacturer, and you'll have a reliable part that functions flawlessly mile after mile. Unlike a traditional throttle body with an accelerator cable, this electronic throttle body by Hitachi utilizes a microcomputer to control the valve opening quickly and accurately. Precision is essential to keep engine torque at a constant level when maintaining the proper air/fuel ratio. A more accurate ETB allows for better fuel economy and emissions performance.

Great product. Easy to install. Noticeable throttle response difference at higher rpm, with a deeper exhaust tone(stock exhaust). The car did idle high(1,000 rpm), I tried the Idle Air Relearn procedure and couldn't get it to work, so I said "F***k it," and disconnected my battery for an hour and a half or two started up and it idled normally with no CEL. Also mine came with a replacement gasket. Worth it!
