AVO Silicone Turbo Inlet MAF Pipe Subaru WRX/STI (GC8) V5/V6 99-00 / Forester GT (SF) 97-02

AVO 1-Piece Wire-Reinforced Silicone Turbo Inlet / MAF Pipe

Engineered specifically for the 1999–2000 Subaru Impreza WRX and STI (GC8 V5/V6) and 1997–2002 Forester GT (SF), the AVO Turboworld one-piece silicone inlet pipe delivers improved airflow and bulletproof reliability for both stock and high-performance turbo setups.

Updated Design for Better Fitment

AVO's engineers have refined the original design with a more pronounced bend at the turbocharger mating point, improving clearance around the TGV (Tumble Generator Valve) area. The result is a tighter, cleaner fit without sacrificing flow — all while keeping the characteristics that made this pipe a favourite among Subaru enthusiasts.

Wire-Reinforced Construction

Upgraded with internal wire reinforcement, this inlet pipe is built to resist collapsing under high vacuum — even with large aftermarket turbochargers and elevated boost levels. Running a stock airbox with increased boost can cause conventional silicone pipes to suck shut, starving the turbo of air and risking serious damage. AVO's wire-reinforced design eliminates that risk entirely.

Maximum Diameter for Maximum Flow

Designed to be the largest pipe that fits within the tight space between the OEM intake manifold and stock turbocharger location, this inlet pipe ensures your turbo setup is never bottlenecked at the intake side. Whether you're running a stock turbo or an upgraded AVO unit, airflow won't be the limiting factor.
