The HKS ETCS-Less Kit, bypasses the ETCS function on the throttle-body on ‘93-‘98 Twin Turbo Supras w/manual transmissions. The ETCS-Less kit prevents traction control activation by eliminating the mechanical “TRAC butterfly plate” assembly of factory ETCS systems and replacing it with precision machined billet aluminum inserts. These inserts allow enhanced airflow characteristics in the throttle body assembly, increasing torque throughout the RPM range.
