Weiand: An American Hot Rod Legend Since 1937

Few names carry as much weight in the world of American performance as Weiand. Founded by Phil Weiand in the 1930s, the company made an immediate mark on the hobby when it introduced the very first aluminum intake manifold — the "High Weiand" — in 1937. That single innovation set the standard for what performance engine components could be, and Weiand has never looked back.

Over the following decades, Weiand became a cornerstone of hot rod and drag racing culture. The company introduced tri-power and four 2-barrel manifolds in the late 1940s, debuted the iconic "Drag Star" log manifold for Hemi engines in 1952, and by 1957 was developing complete blower drives for the GMC 6-71 supercharger. The 1960s and 1970s brought a continuous wave of innovation: the dual-plane "Colt" manifold, the patented "Hi-Ram" series, the legendary "X-CELerator" single-plane line, and the debut of high-performance aluminum water pumps. Today, Weiand is part of the Holley family of brands, continuing its mission of delivering dyno-proven power to street machines and race cars alike.

What Weiand Makes

Weiand's product line is focused and purposeful — every component is engineered to optimize engine airflow and translate directly into measurable horsepower and torque gains. The brand's current lineup covers the most essential performance engine categories for popular Small Block Chevy, Big Block Chevy, Small Block Ford, Big Block Ford, and Gen III/IV LS applications.

• Intake Manifolds: The heart of the Weiand catalog. From street-friendly dual-plane designs like the Stealth series to all-out race units like the Team G and Hi-Ram, there is an engine intake manifold for virtually every performance goal and RPM range.
• Oil Pans: Weiand's performance engine oil pan kits — including drag race-specific designs — are built to maintain proper oil control under hard acceleration, featuring quality construction and a clean, purposeful look.
• Water Pumps: The Action +Plus line of high-flow aluminum engine water pumps, featuring the distinctive "Twisted Snout" design, are engineered to keep temperatures in check even under the sustained stress of performance driving.
• Supercharger Gaskets: Proper sealing is critical when running a blower. Weiand's supercharger gaskets are designed to work seamlessly with Weiand supercharger systems, ensuring a reliable, leak-free seal at all operating conditions.

Built for Street and Strip

What sets Weiand apart is its dual identity: products are engineered to perform on the race strip but remain practical for street-driven builds. Whether you are chasing bracket racing wins or building a weekend cruiser that turns heads at every stoplight, Weiand's lineup offers proven solutions backed by nearly 90 years of performance heritage. For enthusiasts who want to show their pride in the brand, Weiand also offers branded apparel to wear their hot rod allegiance on their sleeve — literally.
