For Yaris GR owners pushing for peak performance, the factory intercooler is often the first bottleneck to rear its head under continuous high-load driving. Heat soak causes intake temperatures to skyrocket, robbing the G16E-GTS engine of its potential.

Today, we’re diving into a comprehensive upgrade kit featuring an upgraded intercooler, an aluminum bumper bracket, and a cast intake manifold. This combination is designed to easily unlock a 10% ~ 12% horsepower increase. Let’s break down the technical features.

1. Core Upgrade: Thicker Intercooler for Superior Cooling
The factory Yaris GR intercooler features a modest core (approx. 645mm x 145mm x 80mm). While adequate for daily driving, it struggles under sustained track abuse.

This upgraded intercooler significantly expands the core volume and optimizes internal fin density. High-performance upgrade solutions in this class typically feature:
1.Over 100% increase in internal volume.
2.63mm inlet/outlet diameters (up from the factory standard).
