Korsh TGV delete plates remove the restrictive factory tumble generator valves to optimise airflow through your Subaru's intake manifold.

With the TGV butterflies gone, these CNC-machined plates reduce intake restriction, improve throttle response and support higher power output on modified engines – essential for builds running larger turbochargers or aggressive tuning. Available in black or polished.
