Eventuri GR86 Carbon Intake

Why upgrade the factory intake

The factory airbox on many modern performance cars does a decent job for everyday use, but it is built around noise regulations, packaging constraints and cost. Sharp internal bends, narrow ducting and resonator chambers all add restriction and trap heat, which softens throttle response and leaves performance on the table once intake temperatures climb.

Eventuri carbon housing design

Eventuri’s patented Venturi housing places the filter inside a smooth, enlarged carbon shell so air can transition through the filter and into the intake tract with minimal turbulence. The system draws from a sealed cold-air feed in a high-pressure area at the front of the car, helping reduce intake air temperatures and maintain consistent performance during repeated pulls, canyon drives or track sessions.

Real gains you can feel

On this platform, independent and Eventuri-backed testing consistently show measurable gains over the stock airbox, particularly once the car is tuned or driven hard for extended periods. Drivers typically notice quicker turbo spool, stronger midrange and a more pronounced induction note under load, without sacrificing OEM-like drivability in daily use.

Fitment and details

• Fits Toyota GR86 and Subaru BRZ
• Developed around the packaging and airflow needs of the FA24 2.4L flat four
• Prepreg carbon fiber construction with smooth internal surfaces for maximum flow
• Patented Venturi housing with a bespoke high-flow filter
• Sealed cold-air ducting to reduce heat soak compared to open-cone engine bay setups
• Direct replacement for the factory airbox and ducting with no permanent modifications required
