Blox Racing BXIM-50203 70mm Billet Throttle Body for Subaru BRZ Scion FR-S Toyota 86 FA20

The Blox Racing BXIM-50203 is a high-performance 70mm billet throttle body engineered specifically for FA20-equipped vehicles including the Subaru BRZ, Scion FR-S, and Toyota 86. This precision-machined throttle body delivers improved airflow over the factory 60mm unit, providing noticeable gains in throttle response and power output throughout the RPM range.

Key Features:

• CNC-machined from high-grade billet aluminum for superior strength and precision tolerances
• 70mm bore diameter increases airflow capacity over stock 60mm throttle body
• Raw aluminum finish can be polished or anodized to match your engine bay aesthetic
• Direct bolt-on replacement for FA20 engines with all necessary mounting provisions
• Includes throttle position sensor mounting provisions for seamless integration
• Compatible with factory ECU and electronic throttle control system

This throttle body is ideal for naturally aspirated builds seeking improved throttle response, or forced induction applications where the factory throttle body becomes a restriction. The raw finish allows customization while the precision CNC construction ensures reliable performance and proper sealing. Professional installation and ECU tuning recommended for optimal results.
