Street Warrior Aluminum Intake Manifolds deliver brutal low-end torque (Idle-5500 RPM) and killer horsepower (1500-5500 RPM). The popularity of larger stroker engines with more efficient cylinder heads and camshafts paved the way for intake manifolds that support such combinations. Designed using computational fluid dynamics software, Street Warrior Intake Manifolds feature square bore or dual pattern carb flanges and a natural, polished, black ceramic coated or Weiand's Everbright finish. Everbright provides a virtually maintenance-free shine that combines vacuum metalizing technology and protective clear coating.
