OVERTAKE Post MAF Hose Kit - Subaru 2008-2014 WRX, 2008-2021 STI, 2009-2013 Forester XT, 2005-2009 Legacy/Outback

What if the air getting to your turbo was actually flowing smoothly?

Your factory post-MAF hose is a wrinkled rubber accordion that disrupts airflow right where it matters most. Those corrugated folds create pockets and turbulence between the MAF sensor and turbo inlet, robbing you of clean airflow and crisp throttle response. The OVERTAKE Post MAF Hose replaces that compromised OEM design with 5-ply reinforced silicone, a smooth interior surface, and a tapered profile that matches your airbox and turbo inlet diameters precisely. Clean air in, better response out. This hose is a heavier duty replacement for OEM Subaru 46013AG020.

What You'll Feel

• Crisper throttle response, especially at partial throttle
• Smoother power delivery through the rev range
• More consistent boost behavior
• That satisfaction of fixing something that should have been right from the factory

Features

• 5-ply Reinforced Silicone Construction - reinforced with stainless steel wire to prevent collapse under vacuum
• Smooth Interior Walls - eliminate turbulence-causing pockets
• Tapered End Design - matches OEM airbox and turbo inlet diameter
  
• Direct OEM Replacement - no trimming or modifications
• No Tune Required - Install the hose and let it rip!
• High-Quality Hose Clamps - Secure fitment and enhanced durability

The Details

The factory rubber post-MAF hose uses corrugated folds to allow flexibility during installation, but those same folds create pockets that interrupt airflow. Worse, the OEM design often creates diameter steps between the airbox outlet and turbo inlet, generating small vortexes that disturb the air right after it passes the MAF sensor. The OVERTAKE silicone hose solves both problems. The smooth interior eliminates the pockets entirely, while the tapered center section transitions cleanly between the airbox and turbo inlet diameters without creating steps. The reinforced silicone is flexible enough for easy installation but rigid enough to hold its shape under full vacuum. It's also far more durable than the factory rubber, which cracks and degrades over time. Pair it with a quality panel filter and you've optimized your factory intake without needing a full cold air intake system.

NOTE: 2015-2017 STI fitment will need OEM sound generator tube deleted, use included plug.
