TOMEI 4 Throttle System Intake Manifolds

In order to build the best EJ engine, the Tomei R&D engineers focused on a highly responsive and powerful setup that still maintained big torque figures. For this objective to become a reality, countless data acquisition and numerous testing was performed on the engine dyno. As a result, the response was like having the throttle body directly connected to the right foot, ad a non-hesitant linear reaction. With the out put numbers at 500HP and 500 ft/lbs of toque, the hard work put into this setup speaks for itself. This product is a must have for the EJ enthusiasts who desire to have an advantage over the rest. Either on the streets or at the track.

Plenum Chamber Features:
  • Specially designed larger capacity for power and response.
  • Very thin, light weight casting and made in Japan!
  • There is added rib support internally for high boost applications.
  • Superb design emphasis on equal air intake distribution.


Throttle Body Features:
  • Increased response and power from the extra air supply with the larger intake plenum chamber.
  • The funnels are made from light weight aluminum for minimal air resistance.
  • The bolts for the throttles are designed to accommodate either size head gasket you decide to
    use since the boxer engines length will change in size depending on your chosen head gasket thickness.
