The COBB post-MAF hose balances form AND function with its smart appearance and turbulence taming characteristics.
The COBB post-MAF Hose joins the stock airbox 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 four-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 maximum vacuum at wide open throttle. Installation is super-easy -- figure maybe fifteen minutes using just a screwdriver.
Black finish.
Fits all 2002-2007 WRX and STI.
