aFe 21-23 Subaru Crosstrek Silver Bullet Throttle Body Spacer Kit

The aFe 21-23 Subaru Crosstrek Silver Bullet Throttle Body Spacer Kit is a precision-engineered performance part designed to enhance engine efficiency and power delivery. Featuring a unique serrated/helix combination design, this throttle body spacer creates intake turbulence that improves fuel atomization for a more complete combustion cycle. This results in increased horsepower, torque, and improved throttle response. Constructed from lightweight, high-strength 6061-T6 billet aluminum, the spacer is precision machined to ensure a perfect fit and durable finish. Additionally, the design reduces the intake whistle commonly associated with helix-only spacers, providing a smoother intake sound.

This throttle body spacer kit is specifically designed for 2021 to 2023 Subaru Crosstrek models. It serves as a direct bolt-on upgrade to the factory throttle body, making installation straightforward without the need for modifications. Ideal for street and daily driving applications, the spacer enhances throttle response and overall engine performance without compromising reliability. The kit includes the billet aluminum spacer and all necessary hardware for installation. This product is a practical upgrade for enthusiasts seeking improved engine efficiency and a subtle performance boost in their Subaru Crosstrek.
