Airtec Stage 3 Intercooler for Toyota Yaris Gr

TECHNICAL DATA

Freshly developed at AIRTEC HQ in the UK, we’re proud to launch our ultimate specification intercooler kit with integrated crash bar design aimed at modified Toyota Yaris GR owners who want the very highest levels of cooling efficiency and performance for track or fast road use.

The challenge

Our initial Stage 1 intercooler was created for modified Toyota Yaris GR models and has gained popularity for upgrades. However, as Yaris GR tuning continues to advance, it became clear that a larger intercooler package would be necessary to handle increased power and extensively modified engines while also remaining compatible with future tuning developments. As a result, we developed the largest intercooler kit possible, utilizing a stepped core design that takes up the entire front grille area. Drawing on our expertise in creating intercooler kits with a replacement crash bar design, we were able to CNC machine billet brackets for secure installation. This new intercooler offers a significant 143% increase in overall capacity compared to the original intercooler (54% larger than our Stage 1 kit), as well as a considerable 121% increase in frontal area over the standard (78% larger than our Stage 1), allowing for optimal air flow. The Stage 3 AIRTEC Motorsport intercooler also

A must have modification for those looking for only the very best for their modified Yaris GR models.

The testing
During track testing at Snetterton Circuit in the UK using our 420bhp AIRTEC Motorsport development car, we logged the inlet and outlet temperatures of both our Stage 1 and Stage 3 intercoolers back-to-back.

The figures showed that at this high level of power, over the course of a hot lap the Stage 1 starts to fight maintaining a stable charge temperature, with a 15-degree range highlighting its battle against the high and sustained levels of boost pressure. However, with the Stage 3 intercooler fitted, the figures showed the larger core with increased air flow provided a much more consistent charge temperature throughout the test, highlighted with just a 5-degree range in temperature.

Verdict: Both intercoolers demonstrate a high level of efficiency, reducing charge air temperature by over 200 degrees and equating to over 90% efficiency, but the Stage 3 could sustain that level for longer, which is crucial for highly tuned cars to run safely for extended periods of time.
