Holley Performance Products is one of the oldest and most recognized names in performance automotive, founded in 1903 in Bowling Green, Kentucky. The brand is best known for its double-pumper and four-barrel carburetors, which have been the standard on American V8 engines for decades. Holley has since expanded into fuel injection systems, intake manifolds, ignition, and a line of performance chemicals — including cleaners and fluids formulated specifically for their own carburetor and throttle body products.
The Holley chemical line is manufactured by PLZ Corp. (a major contract aerosol manufacturer based in Downers Grove, IL) and carries GHS-compliant SDS documentation available through the Holley documents portal at documents.holley.com. Products are 50-state compliant where applicable.
