aFe Silver Bullet Throttle Body Spacer Kit 46-38013 for 2022-2024 Toyota GR86 and Subaru BRZ 2.4L H4

The Serrated/Helix combination design creates intake turbulence in the combustion chamber. This turbulence breaks up the fuel which creates a more complete combustion cycle increasing horsepower, torque and improving throttle response. The Serrated/Helix combination design also reduces intake whistle that occurs with Helix only designs. All Silver Bullet Throttle Body Spacers are constructed from 6061-T6 billet aluminum precision machined for light weight, high strength and perfect fit and finish. Complete with an orange anodized finish, this Silver Bullet throttle body spacer is sure to stand out in the engine bay. This Silver Bullet throttle body spacer uses all factory mounting locations providing stability and a hassle-free installation.

Improve airflow and throttle response with the aFe Silver Bullet Throttle Body Spacer Kit, part number 46-38013. Designed for the 2.4L H4 engine in the Toyota GR86 and Subaru BRZ, this spacer uses a unique serrated and helix combination to create controlled turbulence just before air enters the engine. The resulting airflow helps break up the fuel mixture for more complete combustion, supporting improved horsepower, torque, and throttle response.

Unlike helix-only designs, the serrated/helix entry reduces intake whistle while maintaining increased air speed through the throttle body. The spacer is CNC-machined from lightweight, high-strength 6061-T6 billet aluminum and finished with a durable orange anodized coating for a distinctive engine-bay appearance. It uses factory mounting locations for a stable fit and straightforward installation.
