Subaru Impreza WRX STI GC8 EJ20 Turbo Inlet Intake Hose Induction Hose 96-98 (Ver 3 - 4) (1pc)
This induction hose suits WRX / STI version 3 & 4 models. Made from high temp silicone rubber, it improves the flow over factory.
The stock air induction hose is made of corrugated black rubber that restricts flow and introduces turbulence in the intake. Not only that, it doesn't seem very heat resistant -- we've seen stock induction hoses actually melt on the car!
This induction pipe is made of multi-ply heat-resistant (it can withstand up to 260 degrees!) silicone rubber for much better durability, plus a much smoother intake path. The result is a horsepower increase of 3-8 hp, depending on boost level and modifications.
This hose leads from the air box back to the turbo inlet, traveling UNDER the intake manifold in the process.
