Smoother airflow where it matters most
The factory post-MAF hose on 2008-2014 Subaru WRX and 2008-2021 STI models uses a corrugated rubber design that disrupts airflow immediately after it passes the MAF sensor. Those accordion-style folds create turbulence and dead zones, reducing airflow quality, throttle response, and boost consistency right before the turbo inlet.
The OVERTAKE Post-MAF Hose Kit replaces that compromised OEM design with a smooth-bore, 5-ply reinforced silicone hose. Featuring a carefully tapered profile that precisely matches the airbox outlet and turbo inlet diameters, this upgrade delivers cleaner airflow, improved response, and greater consistency without requiring any tuning.
What You Will Notice
-
Sharper throttle response, especially at partial throttle
-
Smoother and more predictable power delivery
-
Improved boost stability throughout the rev range
-
The confidence of correcting a known factory airflow compromise
Why It Works
While the factory rubber hose allows flexibility during installation, its corrugated design creates airflow disruption and diameter steps that introduce turbulence immediately after the MAF sensor. The OVERTAKE hose eliminates these issues with a smooth internal surface and a gradual taper, allowing air to flow cleanly into the turbo. The reinforced silicone construction maintains shape under full vacuum while offering superior durability compared to ageing OEM rubber. Paired with a quality panel filter, this upgrade optimises the factory intake system without the need for a full cold air intake.
