Product Description

The BLOX Racing BXIM-50203 is a 70mm billet throttle body built for the FA20 engine in the 2013-2020 Subaru BRZ, 2017-2020 Toyota 86, and 2013-2016 Scion FR-S. CNC-machined from billet aluminum, it increases the throttle bore size over the factory unit to allow more incoming air.

Installation is 100% bolt-on and plug-and-play, with no rewiring needed - once installed, the factory ECU performs a relearn to dial in the larger throttle body automatically. It's a straightforward upgrade for BRZ/86/FR-S owners looking for a modest gain in throttle response and airflow without complicating the factory wiring harness.
