PERRIN Throttle Body Hose — 2002–2007 WRX / 2004–2021 STI

The factory throttle body coupler weakens over time and can tear under pressure — especially on higher-mileage cars. PERRIN's replacement is built from 5-ply multi-layer silicone engineered to handle extreme pressures and temperatures for long-lasting, reliable performance. Comes ready to install with the coupler and a pair of clamps.
