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 earlier Stage 1 intercooler was developed to cater for tuned Yaris GR models of the time and has become a popular upgrade. However, Yaris GR tuning potential has since evolved and it became clear we would need a more substantial intercooler package better suited to big power, heavily tuned cars whilst future-proofing them for further tuning development.

The solution
As a result, we developed the biggest intercooler kit we could and made the most of the available space behind the bumper by using a stepped core design that would rise up behind the entire front grille area. Using our experience in developing intercooler kits that integrate a replacement crash bar design, we were able to CNC machine billet brackets that allowed the intercooler to bolt in place. By doing so, the new intercooler offers a huge 143% increase in overall capacity in comparison to the original intercooler (54% bigger than our Stage 1 kit), and also features a colossal 121% increase in frontal area over standard (78% over our Stage 1), which allows it to make the most of the air flow provided.

Together with our high-flow, moulded one-piece cast end tanks to ensure flow is directed correctly and efficiently, the Stage 3 AIRTEC Motorsport intercooler also features an enlarged 60mm inlet to match the outlet, and together the kit offers much greater efficiency and volume over both the standard and our Stage 1 intercoolers, which it proved during testing.

Available in a high-quality powder coated black finish, the comprehensive kit is a direct replacement and comes complete with Pro Hoses silicone connectors to adapt to standard boost pipes – or you can choose our optional and hugely beneficial big boost pipe kit. It also comes complete with all fixtures and fittings, as well as detailed fitting instructions.

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.
