GrimmSpeed Red Post-MAF Hose Kit 2015-2021 WRX

DESCRIPTION Thie GrimmSpeed Red Post-MAF 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. WHY? The kit now comes with a beautiful textured red powder coat finish, which not only looks great but also provides extra durability and protection against the elements. The GrimmSpeed Post MAF Pipe Kit is a must-have for any WRX owner looking to spruce up their engine with an OEM+ look and fitment.
