The Eventuri Carbon Turbo Inlet Tube is a high-flow turbo inlet upgrade for the Toyota GR Yaris and GR Corolla G16E-GTS platform. Designed to reduce restriction between the intake system and turbocharger, this enlarged carbon inlet tube increases available airflow volume while maintaining a smoother path into the compressor inlet.

By increasing internal volume from approximately 1,300 cm³ to 2,200 cm³, Eventuri creates a larger air reservoir ahead of the turbocharger. This nearly 70% increase in volume helps improve turbo response, supports earlier peak boost, and delivers measurable gains in mid-range torque and peak power when paired with the proper setup.

Key Features

• Nearly 70% More Inlet Volume: Internal volume increases from approximately 1,300 cm³ to 2,200 cm³.
• Reduced Turbo Inlet Restriction: Enlarged carbon tube improves airflow between the intake and turbocharger.
• Improved Turbo Response: Larger pre-turbo air volume helps the turbo draw from a less restrictive air supply.
• Proven Performance Gains: Eventuri dyno testing showed gains of up to 14whp and 19 ft-lb of torque through the mid-range.
• Peak RPM Gains: Testing also showed approximately 9whp and 9 ft-lb gained at peak RPM.
• Pre-Preg Carbon Construction: Rigid carbon fiber tube resists deformation under turbocharger vacuum.
• Bespoke Nitrile Elbow: Provides a durable, high-flow connection between the carbon tube and turbo area.
• CNC-Machined Aluminum Flange: Bolts directly to the factory turbocharger inlet for precise fitment.
• Modular Turbo Flange Design: Allows future compatibility with supported larger hybrid turbocharger applications using alternate flange options.
• Gloss or Matte Finish Options: Choose the carbon finish that best matches your engine bay setup.

Why We Like It

This is the natural next step for GR Corolla and GR Yaris owners already running the Eventuri intake system. The factory turbo inlet creates a restriction right before the turbo, especially through the lower bend. Eventuri solves that by increasing volume, smoothing the airflow path, and using rigid pre-preg carbon that will not collapse under vacuum. It is functional, beautifully made, and completes the intake-side airflow path.

Design & Performance

Eventuri focused on increasing the volume of air available immediately before the turbocharger while improving airflow through the restrictive lower section of the factory inlet. The enlarged carbon tube gives the turbocharger a larger and smoother air supply, helping reduce wastegate duty cycle, improve throttle response, and support stronger mid-range performance.

Compatibility & Disclaimers

Designed for compatible Toyota GR Yaris and Toyota GR Corolla G16E-GTS applications. Performance gains may vary depending on intake setup, ECU calibration, fuel quality, turbocharger configuration, and supporting modifications. Hybrid turbo applications may require an alternate modular flange. Always verify vehicle fitment, turbo compatibility, and installation requirements before ordering.
