The Volant Pro5 closed‑box air intake for 2014–2015 GMC Sierra/Chevy Silverado 2500/3500HD (6.0L V8) uses a reusable five‑layer Pro5 oiled cotton gauze filter pre‑oiled for immediate use and a sealed box to shield inlet air from underhood heat. Volant’s design increases airflow compared with stock, offers extended service intervals—up to about 40,000 miles depending on conditions—and includes a smoked acrylic lid, hardware and bolt‑on installation under one hour.
