The CSF Stepped Core Intercooler for Toyota GR Corolla and GR Yaris is a high-performance drop-in upgrade that increases core volume and surface area for lower charge air temps. It uses a Tube & Fin stepped core with TIG-welded cast aluminum end tanks, and includes motorsport-grade 5-ply silicone hoses and bead-lock clamps. OE ducting needs minor trimming; real-world testing by MotoIQ validates the gains.
