Features & Product Details

RallySport Direct proudly carries a great selection of quality aftermarket performance products brought to you by GrimmSpeed. 

 

This is the GrimmSpeed Post MAF Hose Kit. This post-MAF hose combines durable multi-layer silicone fiber and smooth interior walls and CAD technology that makes for an excellent high-performance upgrade over the factory OEM post-MAF hose. This is achieved by eliminating the pockets and corrugated folds in the OEM design to improve the overall flow and throttle response. 

 

 

TECHNICAL:

  • Reinforced silicone construction
  • The design removes the OEM corrugated folds and the pockets to create a smooth interior wall
  • Designed with a tapered center portion to make sure the diameter matches the OEM air box and turbo inlet
  • The design eliminates mismatched hose diameter which can create steps that will cause airflow trajectories and small vortexes 
  • The shape of the hose was optimized through CAD Flow Simulation Testing to generate a smoother flow path
  • The removal of the corrugated folds adds a significant reduction in vorticity to calculate the highest flow efficiency
  • The tapered center portion in the design has an emphasis on vorticity to reduce as much turbulence as possible

    •  

     

    DETAILS:

  • Black finish
  • 4-ply reinforced silicone hose construction
  • CAD-optimized center section to match airbox and inlet for seamless flow
  • GrimmSpeed logo stamped on the airbox side of the hose
  • Includes Breeze hose clamps for the installation

    •  

     

    NOTE:

  • Designed with OEM Sound Tube Generator Delete
