The new Grams 72mm Drive-By-Wire Electronic Throttle Body is the perfect upgrade from the factory 65mm Scion/Subaru/Toyota throttle body; delivering a 48% increase in airflow. Each throttle body includes all new components including a CNC machined billet 6061-T6 aluminum housing with a precision-honed oversized bore, a high-torque servo motor, and a proprietary Non-Contact Hall Effect TPS sensor. To ensure the best performance, throttle response, and driveability, each TPS sensor is calibrated to meet the specific requirements of the vehicles engine management system. The Grams electronic throttle body is an ideal solution for both modified and stock engines with increased airflow demands.


The Grams Performance & Design DBW Throttle Body's are sold complete and ready to go, straight from the box. This is the only complete system on the market today. No Core Exchange Required.



  • 50% Increase in Airflow Over Stock 64mm Throttle Body
  • Precision Honed Oversized 72mm Bore with Tapered 80mm Entry
  • CNC Machined Billet 6061-T6 Aluminum Housing
  • Aluminum Throttle Plate
  • Factory Programmable Non-Contact Hall Effect TPS
  • Optimized TPS Response Curve
  • High-Precision Servo Motor
  • Thermal Gasket, Plug & Play Adapter Harness, and Hardware Included
Due to the larger size of the throttle body the factory intake tube is a tight fit. We recommend using a small amount of WD40 on the lip of the throttle body as well as the inside of the intake tube to help slip it on. If you already have an intake system that came with a coupler 3.00" or smaller, you may want to consider purchasing the Grams Performance & Design G09-99-3130 (part number) - 3.15" to 3.00" coupler.
