The Volant PowerCore closed-box cold air intake for 2001–2004 Chevrolet Silverado 2500HD 6.6L V8 applications improves intake flow while protecting the filter. It uses a Donaldson PowerCore Ultra‑Web filter (99.96% efficient, maintenance-free up to 150,000 miles) housed in a closed box with an insulated metallic lid, stainless steel clamps and easy access. Bolt-on installation typically takes under one hour and it outflows the stock intake.
