AGT 57mm "LE" Turbocharger | Mitsubishi Evo X

Evo X AGT 57mm "LE" Turbocharger

The AGT 57mm LE Turbocharger for Mitsubishi Evo X is a high-output stock frame upgrade engineered for serious 4B11T builds targeting strong midrange power and impressive top-end performance. Flowing up to 65 lbs/min, this turbo offers an ideal balance of spool response and horsepower capability for aggressive street and track-driven Evo X setups.
