GrimmSpeed Black Post-MAF Hose Kit 2015-2021 WRX

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.

WHY?

The OEM rubber hoses require sharper angels and corrugated structural folds as part of their design. This contributes to uneven airflow through the hose with high and low pressure spots. The GrimmSpeed Hose design supports a minimal curve transition and is perfectly smooth inside, resulting in more consistent airflow to the turbo, creating more consistent power. 

FEATURES:

• Black finish

• 4-ply stainless steel reinforced silicone construction

• OEM fitment

• High-quality Breeze hose clamps
