Chevrolet Suburban Performance Air Intake - CORSA Performance - Closed Box with MaxFlow 5 Oiled Filter ('21-'25). This closed-box intake replaces the factory airbox to improve airflow while protecting the filter and supporting reliable day-to-day use.

The CORSA closed-box system uses Volant's MaxFlow 5 five-layer oiled cotton gauze filter, pleated between aluminum screens and shipped pre-oiled for immediate use. The assembly features a smoked acrylic see-through lid so you can visually inspect the filter without disassembly. Built to outflow the stock intake, the design focuses on consistent breathing and long filter service intervals (up to 40,000 miles depending on driving and conditions). The system bolts on in under an hour and is constructed to protect the filter from road debris. Made in the USA and backed by a lifetime warranty. Note: CARB EO unavailable.
