GrimmSpeed Post MAF Hose Kit Black WRX 15-21 | 125023.1

Description

This is the GrimmSpeed Post MAF Hose Kit. This hose kit has been designed to replace the OEM hose to increase the flow to improve the overall power and response. This hose features durable 4-ply silicone construction that is heat resistant and features smooth interior walls that replace the corrugated folds of the OEM design. Additionally, this hose is flexible without affecting the structure to make this simple to install without the risk of collapsing under vacuum.

This hose also features tapered end portions making sure that the in er diameter will match the OEM air box and turbo inlet. A mismatched diameter will create steps that interrupt the airflow trajectories and will create small vortexes in the post-MAF hoses. Grimmspeed’s design will prevent these issues.
