Grams Performance DBW Electronic Throttle Body
2012–Present Scion FR-S, Subaru BRZ, Toyota 86
G09-12-0100
Overview:
The Grams Performance DBW Electronic Throttle Body is a high-quality upgrade designed specifically for the 2012 and newer Scion FR-S, Subaru BRZ, and Toyota 86 models. This throttle body is engineered to meet the increased airflow demands of modified engines, delivering improved throttle response and significant horsepower gains across the power band. Ideal for enthusiasts running naturally aspirated or forced induction setups, it provides a crucial performance enhancement by increasing the throttle bore size from the stock 64mm to a substantial 72mm.
Whether you are building a high-performance street car or a track-focused machine, this throttle body offers a reliable and efficient solution to unlock your engine’s full potential. Its plug-and-play design ensures a straightforward installation process without the need for extensive modifications or tuning.
Key Features:
The Grams Performance DBW Electronic Throttle Body combines advanced technology and precision engineering to deliver superior performance and durability. Key features include:
- Oversized 72mm bore, providing a 50% increase in airflow over the stock 64mm throttle body
- Drive-By-Wire (DBW) electronic throttle system for precise throttle control and improved response
- Factory programmable, non-contact Hall Effect Throttle Position Sensor (TPS) for accurate and reliable input
- CNC machined billet 6061-T6 aluminum housing for strength and lightweight construction
- Precision honed bore to ensure smooth airflow and optimal sealing
- High precision servo motor for consistent and responsive throttle actuation
- Aluminum throttle plate designed for durability and minimal airflow restriction
- Includes spacers, plug-and-play wiring harness adapter, and all necessary hardware for installation
- Optimized TPS response curve for enhanced drivability and throttle modulation
Construction & Design:
Built from premium CNC machined billet 6061-T6 aluminum, the Grams Performance throttle body offers exceptional strength and corrosion resistance while maintaining a lightweight profile. The precision honed 72mm bore ensures smooth airflow and reduces turbulence, contributing to improved engine efficiency and power output. The aluminum throttle plate is engineered for durability and minimal drag, while the high precision servo motor guarantees consistent throttle actuation under all driving conditions. The non-contact Hall Effect TPS enhances reliability and eliminates wear points common in traditional potentiometer sensors.
Performance & Sound
By increasing the throttle bore size by 50%, this throttle body significantly improves airflow, which translates into noticeable horsepower gains throughout the entire power band. Naturally aspirated engines benefit from enhanced throttle response and smoother power delivery, while forced induction setups see even greater performance improvements due to reduced intake restriction. The optimized TPS response curve also contributes to a more immediate and linear throttle feel, enhancing driver confidence and control. While the throttle body itself does not alter exhaust sound, the improved engine breathing can complement other performance modifications for a more aggressive overall driving experience.
Installation & Fitment:
The Grams Performance DBW Electronic Throttle Body is designed as a direct fit replacement for the 2012 and newer Scion FR-S, Subaru BRZ, and Toyota 86 models. Installation is straightforward, with included spacers and a plug-and-play wiring harness adapter simplifying the process. No major modifications or custom tuning are required for most applications, making it an accessible upgrade for enthusiasts of all skill levels. Proper calibration of the throttle system may be necessary to ensure optimal performance and compatibility with the vehicle’s ECU.
