The AIRTEC Motorsport Enclosed Air Induction is a fully enclosed intake system developed for the Toyota Yaris GR. The kit replaces the entire airbox and is designed to combine maximum airflow with low intake temperatures. Thanks to the GRP composite housing, large Group A-style cotton filter, and 80mm MAF housing, heat buildup is minimized and response is improved.
Advantages
• Closed airbox for low intake temperatures
• Continuous supply of cold air via front intake
• Larger high-flow cotton filter
• Improved throttle response
• Increased intake noise
• High-gloss black finish for a neat engine compartment
• Direct replacement without drilling or grinding

Frequently Asked Questions
Is drilling or grinding required during installation?
No, the kit is completely bolt-on.
Is this system better than an open filter intake?
According to tests, the closed system offers better thermal control and additional power gains.
Is tuning required?
No, but additional power gains can be achieved in combination with tuning.
