Intercooler - HKS - R Type - GR YarisHKS Intercooler R Type GR Yaris HKS concept is OEM fitment for GR Yaris but also improved cooling performance Although it is a stock replacement, we designed it bigger for future power improvement. It is also effective when driving on the tracks. The use of a new multilayer core minimizes weight, reduces pressure loss, and improves cooling performance. The increased height and thickness improves cooling performance for modified and hard driven cars.
