Constructed from aluminum, this oval air cleaner delivers the polished finish that defines high-end engine bay customization. The ribbed base pattern provides structural rigidity while maximizing visual impact—a hallmark of Billet Specialties' attention to detail.

This large oval flag air cleaner reflects that expertise, offering show-quality finishing and engineered proportions that integrate seamlessly into both mild and aggressive custom builds.
