Improve gas flow and increase performance with our Toyota GR yaris turbo heat shield. Our GR Yaris turbo heat shields are designed to isolate the hot gases from the turbocharger and retain the heat within the exhaust gas itself. Hotter gas dissipates heat faster, thereby improving spool and throttle response. Insulating the hot side of the turbocharger also helps reduce the amount of heat the turbocharger dissipates into the engine and intake manifold. Over time, a cooler air intake results in higher performance and more consistent power figures.
