Say hello to the new COBB Post MAF Hose for the '02-'07 Subaru WRX! The COBB Post MAF Hose balances form AND function with its smart appearance and turbulence taming characteristics. It 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. The sleek exterior is easy on the eyes while the slick interior is airflow friendly. Make your turbo happy!
