BXIM-50203-BK

Overview:

The BLOX Racing 70mm Billet Throttle Body is a precision-engineered upgrade designed specifically for the Subaru BRZ (2013–2020), Toyota 86 (2017–2020), and Scion FR-S (2013–2020). Crafted to enhance throttle response and optimize airflow, this throttle body is ideal for enthusiasts seeking improved engine performance and a more engaging driving experience. Its direct fitment ensures seamless integration with the factory intake system, making it a reliable choice for both street and track applications.

Whether you are upgrading your naturally aspirated setup or complementing other performance modifications, the BLOX Racing billet throttle body delivers consistent throttle actuation and increased airflow capacity, helping your engine breathe more efficiently.

Key Features:

This throttle body combines advanced engineering with high-quality materials to provide a durable and effective performance upgrade. Key features include:

  • 70mm bore diameter for enhanced airflow and throttle response
  • Precision CNC billet aluminum construction for superior strength and lightweight design
  • Black anodized finish for corrosion resistance and a sleek appearance
  • Direct bolt-on fitment for Subaru BRZ (2013–2020), Toyota 86 (2017–2020), and Scion FR-S (2013–2020)
  • Improved throttle plate design to reduce turbulence and maximize air intake efficiency
  • Compatible with factory sensors and throttle cables for easy installation
  • Enhanced durability to withstand high-performance driving conditions

Construction & Design:

The BLOX Racing billet throttle body is meticulously crafted from high-grade aluminum using CNC machining processes. This ensures tight tolerances and a perfect fitment that maintains OEM reliability while delivering performance gains.

Installation of the BLOX Racing billet throttle body is straightforward, requiring no modifications to the factory intake manifold or throttle linkage. It is designed as a direct replacement for the stock throttle body on the specified Subaru BRZ, Toyota 86, and Scion FR-S models. Enthusiasts with basic mechanical skills can complete the swap using common hand tools, and the throttle body retains compatibility with all factory sensors and electronic components.

For optimal performance, it is recommended to inspect and clean the intake system during installation. No additional tuning is strictly necessary, but performance gains may be maximized with supporting modifications and ECU calibration.

What's Included:

  • 1 x BLOX Racing 70mm Billet Throttle Body (Black Anodized)
  • Installation hardware and gaskets (where applicable)
  • Detailed installation instructions

Ideal For:

This billet throttle body is perfect for Subaru BRZ, Toyota 86, and Scion FR-S owners looking to improve throttle response and airflow without extensive modifications. It suits enthusiasts upgrading naturally aspirated engines, those preparing their vehicles for forced induction, or anyone seeking a reliable, high-quality replacement throttle body for enhanced performance and durability.
