Carburetor & Injection Air Boxes

Air boxes for carburetors and ITB systems are a key part of engine builds in motorsport, rally and circuit. Compared to OE intake systems, a sealed air box fed with fresh air provides even supply to each cylinder, reduces turbulence and stabilizes intake flow to maximize efficiency. On carburetor setups and individual throttle body fuel injection, a racing air box smooths airflow, can create beneficial mild pressure, and keeps intake air cooler than open trumpets that draw hot engine bay air. This improves throttle response, rev climb and usable power across the rev range, from low RPM to extreme high RPM in competition. A selection of racing air boxes is available for prepared engines, compatible with brands such as Jenvey, ITG, Pipercross and Green. Whether for asphalt rally, gravel rally, circuit, drift or high performance tuning, an air box is essential for drivers and builders seeking reliability, performance and compliance with motorsport regulations
