The Roto-Fab Big Gulp Cold Air Intake is a high-capacity intake system designed to maximize airflow for the Chevrolet Camaro ZL1 equipped with the supercharged 6.2L LT4 engine. Featuring a massive intake tube and oversized air filter, this system significantly reduces restriction compared to the factory intake, allowing the LT4 to pull in more air under boost. The result is improved throttle response, increased airflow efficiency, and the potential for measurable horsepower gains when paired with proper tuning. Engineered with OEM-level fitment and sealing, the Big Gulp intake maintains excellent drivability while delivering a more aggressive supercharger sound. For high-performance builds or pulley-upgraded ZL1s, this intake becomes a critical airflow upgrade rather than just a cosmetic add-on.
