The Weiand Speed Warrior features long, separated runners for bottom-end and mid-range power, plus a special runner design and larger plenum to flow the air needed for high-rpm horsepower. All of this usable power makes this intake perfect for your street and strip hot rod! Weiand developed the first ever aluminum intake manifold in 1937. Thirty years later Weiand developed complete blower drives for the GMC 6–71 supercharger. Today, Weiand is still at the forefront of intake manifold and blower development as well as high flow water pumps. To make more power you have to get more air to your engine. Look to Weiand as your power source!

This manifold is part of the Weiand Nostalgia Series of intake manifolds. Weiand Nostalgia Series intake manifolds are made using the original tooling, and may have minor appearance imperfections that do not affect the functionality of the part. These minor blemishes are a natural part of the casting process when using the original sand casting tooling. Weiand Nostalgia series intakes are proudly cast and machined in the USA. We support all areas of the vintage, show, and nostalgia car hobby, and want to continue to produce these lower volume manifolds using the original tools. There is no need to search for that vintage intake at swap meets or on the internet when you can buy the real deal new from Weiand! If you are not satisfied with a Nostalgia Series intake

Looking for the ultimate in high performance street intakes? A lot has changed in the performance world since the time many of the manifolds on the market were introduced 20+ years ago. With the popularity of larger stroker engines and more efficient cylinder head/cam designs has come a need for manifolds to support these larger displacements. Weiand recognized this and has developed a new line of Street Warrior™ manifolds designed with Computational Fluid Dynamics (CFD) to generate maximum horsepower and torque out of today’s engines. Dyno testing of the new Weiand 8124 found an additional 14 peak HP and 13lb/ft torque over brand E – p/n 2121.  Average torque was increased by 9.5 and HP by 8.5 from 2,200 to 6,000 RPM! Testing was performed on a 302 with high flow 58cc heads, 268/279 dur/.522 lift Lunati cam P/N 51023, 600 cfm carb & 1-5/8” headers.
