Description
Precision-engineered TGV (Tumble Generator Valve) delete plates from Korsh, designed to eliminate restrictive factory tumble generator valves and optimize airflow in your Subaru's intake manifold.
By removing the TGV butterflies, 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.
