AIRTEC Motorsport Enclosed Carbon CAIS for Toyota Yaris GR Gen 1
AIRTEC Carbon Closed Air Induction System
Part No: ATIKYGR03 – Toyota GR Yaris
Developed in-house at AIRTEC HQ in the UK, the AIRTEC Carbon Closed Air Induction System is a complete replacement airbox solution designed specifically for the Toyota GR Yaris.
Built for both fast road and track use, it focuses on increasing airflow while maintaining low intake temperatures for improved power, throttle response, induction sound, and engine bay aesthetics.
Constructed from lightweight carbon fibre for superior thermal efficiency, the sealed airbox houses a large Group-A style cotton air filter that draws cold air directly from the front intake. This closed design minimizes heat soak and ensures consistently lower intake temperatures compared to open filter systems.
The kit includes an 80mm replacement MAF housing and rear intake pipe, both finished in durable black powder coat, along with high-quality silicone connectors and all required fittings. It arrives pre-built for direct installation with no drilling or cutting required.
Proven Performance Gains
- AIRTEC Dyno Test: 335bhp (5bhp more than AIRTEC’s open filter kit)
