Product Details

The Weiand 8125P Street Warrior intake manifold is engineered for small block Chevy V8 engines seeking strong street performance from idle to 5,500 RPM. This dual plane, low-rise design delivers excellent throttle response and torque across the useable RPM range, making it ideal for daily drivers, street machines, and mild performance builds.

Key Features:

  • Dual plane design optimized for idle to 5,500 RPM power band
  • Universal dual pattern carburetor flange accepts both spread bore (Quadrajet) and square bore carburetors
  • Runner geometry optimized using Computational Fluid Dynamics (CFD) software for even fuel and air distribution
  • Port dimensions: 1.84" height x 1.12" width
  • Manifold height: 3.50" front, 4.50" rear
  • Sand cast aluminum construction with precision CNC machining for accuracy and consistency
  • Low-rise profile for hood clearance compatibility

The Street Warrior series represents Weiand's commitment to delivering high-value performance parts that provide more power per dollar. The optimized runner design ensures balanced fuel distribution to all cylinders, while the dual plane configuration maintains strong low-end and midrange torque characteristics that make this manifold exceptionally streetable.
