Filtration, airflow, and heat are the three factors that matter most when designing an intake system for a turbocharged engine, and the factory GR Yaris airbox leaves genuine room for improvement on all three fronts. A restrictive filter element and tight ducting both limit the amount of air reaching the turbo, while the airbox's positioning within the engine bay leaves it exposed to radiated heat that raises intake air temperatures under sustained hard driving.
do88's replacement addresses this with a sealed design that keeps hot engine bay air out while opening up genuinely improved airflow through the system. A larger, higher-flow filter element paired with smoother, less restrictive ducting delivers more air to the turbo with less effort, translating into a genuinely more responsive engine and consistently cooler intake air temperatures, particularly noticeable during repeated hard pulls or spirited driving where the factory system starts to show its limits.
Works with: OEM mounting points and turbo inlet connections. Genuine drop-in fitment.
Why Choose This Intake System
Fully sealed design, keeps hot engine bay air out of the intake system
Larger, higher-flow filter element than the restrictive factory unit
Smoother, less restrictive ducting for genuinely improved airflow
Consistently cooler intake air temperatures under sustained hard driving
