GrimmSpeed Post MAF Hose Kit with OEM Sound Generator Tube Delete


Highlights

  • Black or red 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
  • 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

Add Some Style and Performance Under Your Hood

Its Not Just Any Hose

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.
