PIII GR Yaris MAP Sensor Cooling Duct

PIII GR Yaris MAP Sensor Cooling Duct Kit The PIII GR Yaris MAP Sensor Cooling Duct Kit is an engineered OEM+ solution developed to eliminate a hidden heat-soak bottleneck on the Toyota G16E-GTS engine platform. After intensive development and analyzing the exact cooling strategies used by Toyota Gazoo Racing during 24-hour endurance racing at the grueling Nürburgring, we created a direct-fit duct that prevents ECU-induced power cuts without compromising vehicle safety or reliability. Unlike raw open prototypes that expose critical electronics to the elements, the PIII Cooling Duct uses a sealed, aerodynamically optimized design that shields your sensor from weather while delivering a continuous stream of ambient air. The result is stable sensor temperatures, consistent engine output, and maximum performance during hot track days or hard road driving. Main benefits Prevents power drops by keeping MAP sensor temperatures well below critical thresholds Integrated water separation aerodynamics protect electrical components in heavy rain Reverses power degradation caused by factory heat soak across the G16E-GTS platform Constructed from high-strength, chemical-resistant automotive PA12 material Lightweight, sleek OEM+ appearance that matches the factory engine bay styling No permanent modifications or bumper removal required for installation Effortless mounting to the vehicle chassis using only a single bolt The Problem: G16E-GTS Heat Soak & Power Loss The Toyota G16E-GTS engine platform features a built-in safety calibration that directly fights track-day performance. The MAP sensor, located on the throttle body, acts as a heat sponge, triggering ECU power cuts when temperatures exceed 55°C (131°F). This issue affects both stock and heavily modified engines. The PIII Cooling Duct uses CFD-engineered aerodynamics to shield the sensor from water while providing constant, ambient cooling air.
