Boomba Racing is proud to offer the Throttle Body & Intake Manifold Spacer Combo Kit for the 2023+ Toyota GR Corolla. CNC machined from premium billet aluminum, this combo kit increases the volume of air entering your engine, resulting in improved cylinder filling at lower RPMs, smoother throttle response, and earlier boost. By extending the intake charge wave pulse, these spacers help deliver quicker torque and stronger mid-range power, making the GR Corolla even more fun to drive. Dyno testing has shown performance gains of up to 23 horsepower and 5 ft-lbs of torque when both spacers are installed together. In addition to increased power, the spacers also improve fuel efficiency by enhancing the engine's airflow and reducing throttle lag. The kit includes all necessary corrosion-resistant hardware for a straightforward, direct bolt-on installation—no tuning required. Available in Blue, Red, Black, or Natural Aluminum finishes to match your engine bay style.
