Eventuri Carbon Turbo Inlet Tube (Gloss) - Toyota GR Corolla 2023+ / GR Yaris 2021+

Description

The Eventuri Carbon Turbo Inlet Tube for the Toyota GR Yaris and GR Corolla is engineered to reduce restriction between the intake system and turbocharger, increasing available airflow volume while maintaining a smooth path into the compressor inlet. Designed for the G16E-GTS platform, the enlarged carbon turbo tube improves turbo response, helps the engine achieve peak boost earlier in the RPM range, and supports measurable gains in both mid-range torque and peak power.

During development, Eventuri focused on two key areas: increasing the internal air volume available immediately before the turbocharger and improving airflow through the critical lower bend of the factory inlet. The OEM turbo tube is particularly restrictive in this section, limiting the volume of air the turbocharger can draw from under load. Eventuri increased the internal volume from approximately 1,300 cm3 to 2,200 cm3, an increase of nearly 70%, while reshaping the lower section to create a larger and less restrictive air reservoir ahead of the turbocharger.

This increased volume allows the turbocharger to draw from a larger supply of air with less restriction, reducing wastegate duty cycle and improving throttle response. Dyno testing demonstrated gains of up to 14 whp and 19 ft-lb of torque through the mid-range, with gains of approximately 9 whp and 9 ft-lb at peak RPM.

The main inlet tube is manufactured from rigid pre-preg carbon fiber to resist deformation under the vacuum generated by the turbocharger. The carbon tube connects to a bespoke nitrile elbow and a precision CNC-machined aluminum flange that bolts directly to the factory turbocharger inlet. This combination provides a durable, high-flow connection while preserving precise fitment throughout the assembly.

Eventuri also designed the GR Yaris / GR Corolla turbo inlet with future turbocharger upgrades in mind. The CNC-machined turbo flange is modular, allowing the inlet system to be adapted for compatible larger hybrid turbochargers by replacing the flange rather than the complete carbon tube. Alternative flange options are available separately as supported applications are introduced.
