GMC Sierra Performance Air Intake - CORSA Performance - Closed Box with MaxFlow 5 Oiled Filter - `19-`25. This closed-box intake for 2019–2025 Sierra models replaces the factory system with a free-flowing design and a pre-oiled MaxFlow 5 filter for improved airflow and long service intervals.

Designed for drivers who want reliable performance gains without guessing, this CORSA system pairs a rugged closed airbox and a Volant MaxFlow 5, 5-layer oiled cotton gauze filter. The smoked acrylic see-through lid protects the filter while letting you inspect it visually. The filter ships pre-oiled and is engineered for high airflow and extended maintenance intervals (up to 40K miles depending on driving conditions). The kit is a direct bolt-on and installs in under an hour.
