Flashark Cold Air Intake Kit for 1999–2006 Chevy Silverado & GMC Sierra 4.8L / 5.3L / 6.0L Vortec V8
Built for the compatible Chevrolet and GMC Vortec V8 applications listed below, this Flashark cold air intake kit replaces the factory intake path with a 4-inch polished aluminum intake tube, a washable oil-free dry filter, and a stamped-steel heat shield.
It is a practical upgrade for owners who want reusable dry filtration, a cleaner aluminum intake layout, and clear vehicle-specific information—without relying on unverified horsepower or torque promises.
