Blox Racing BXIM-50203-BK 70mm Billet Throttle Body Black Anodized FA20

The Blox Racing BXIM-50203-BK is a precision-machined 70mm billet aluminum throttle body designed specifically for FA20 engines found in the Subaru BRZ, Scion FR-S, and Toyota 86. This performance upgrade increases airflow over the factory throttle body, helping to improve throttle response and support higher horsepower goals on modified engines.

Key Features:

• 70mm bore diameter for increased airflow capacity
• CNC-machined from high-quality billet aluminum for strength and precision
• Black anodized finish for corrosion resistance and aggressive styling
• Direct bolt-on replacement for FA20 engines
• Includes necessary gaskets and hardware for installation
• Designed to work with factory or aftermarket intake manifolds

This throttle body is an ideal upgrade for naturally aspirated or forced induction FA20 builds seeking improved breathing and throttle response. The larger bore diameter reduces restriction in the intake tract, allowing the engine to draw more air under high-load conditions. The durable anodized finish ensures long-lasting performance in demanding motorsports environments.
