Construction & Design:

The throttle body spacer is machined from premium 6061-T6 billet aluminum, a material known for its excellent strength-to-weight ratio and resistance to heat and corrosion. This ensures long-lasting performance even under demanding engine conditions. The unique Helix Bore design inside the spacer creates a controlled swirling motion of the incoming air charge, which increases air velocity and promotes better mixing with fuel. This engineering innovation leads to improved combustion efficiency and enhanced engine response.

Every unit is precision-crafted to exacting tolerances, ensuring a perfect fit and seamless integration with the factory throttle body assembly. The included gaskets and hardware maintain a secure, leak-free seal, preserving engine integrity and performance.

Performance & Sound

The AirAid Throttle Body Spacer primarily improves low-end and mid-range torque, resulting in a noticeable increase in throttle responsiveness and smoother acceleration from idle through moderate RPM ranges. While it does not alter exhaust sound significantly, the enhanced combustion efficiency can contribute to a more refined engine note during part-throttle operation. Drivers will appreciate the more immediate power delivery and improved drivability in everyday conditions.

Installation & Fitment:

Installation is straightforward and can typically be completed in under one hour using basic hand tools. The spacer fits directly between the throttle body and intake manifold without the need for any drilling, cutting, or permanent modifications. All necessary gaskets, brackets, and hardware are included to ensure a secure and proper fit. This makes the AirAid Throttle Body Spacer an accessible upgrade for both professional installers and experienced enthusiasts.

Designed exclusively for the 2005–2010 Scion tC and 2008–2015 Scion xB2 equipped with the 2.4L 2AZ-FE engine, this spacer guarantees compatibility and optimal performance gains for these specific models.
