AIRTEC Motorsport Intercooler Upgrade for Toyota Yaris GR Gen 1

If your Gen 1 GR Yaris loses its edge after a few hard laps or a long fast drive, the small factory intercooler is a likely cause. AIRTEC's intercooler upgrade is a direct replacement that fits behind the standard bumper with no cutting. It's the sensible first cooling upgrade for a road car with a map or a track-day car.

How it compares with the standard intercooler

• Capacity: 11.7 litres vs 7.1 litres, a 64% increase
• Frontal area: 11,590cm² vs 8,917cm², a 30% increase
• Stepped core from 110mm to 70mm deep, 610mm × 190mm
• 50mm inlet kept for crisp throttle response, 60mm outlet for less restriction
• Cast one-piece end tanks with an internal air diverter to spread flow across the core
• Pro Hoses silicone connectors, all fixtures and a step-by-step photo guide included
• Goes back to standard with no issues if you ever sell the car
• AIRTEC part number: ATINTYGR1

Stage 1 or Stage 3?

This Stage 1 kit suits most road cars and occasional track days. If you're running big power, AIRTEC's Stage 3 intercooler has more than double the factory capacity, but it needs a different oil cooler. The Stage 1 intercooler does work with AIRTEC's standard oil cooler kit. For pipework to match, see the Big Boost Pipe Kit for the Stage 1 intercooler.

Questions we get asked

Does it need any cutting?
No. It fits behind the original bumper with no trimming or cutting.

Will I notice it on the road?
It's most noticeable when the car is working hard: repeated pulls, hot days and track sessions, where it helps keep intake temperatures and power consistent.
