COBB Tuning Post MAF Hose for 2002-07 Subaru WRX / STI & 2004-07 Forester XT (Black)

The COBB Post MAF Hose for the 2002-07 Subaru WRX / STI balances form and function with its smart appearance and turbulence taming characteristics. The COBB Post MAF Hose joins the stock airbox (or optional COBB SF Intake) to the turbo inlet tube by replacing the stock corrugated rubber piece, arguably one of the most aesthetically challenged OEM parts in the engine bay. While the sleek exterior is easy on the eyes, the slick interior is friendly to airflow, feeding a smooth column of air to the turbo.

The 4-ply silicone construction has the right compliance to bridge the chassis mounted airbox to the violent motion of a boxer engine being driven in anger, while the steel reinforcement prevents collapse when the turbo is drawing the maximum vacuum at wide open throttle.

• Replaces corrugated OEM tube, smoothing airflow to the turbo
• 4 ply silicone with steel reinforcement construction
• Compliance absorbs relative motion between engine and chassis Steel reinforcement prevents collapse under maximum demand
• Stealth Black
