When pushing the limits of your Toyota — whether on the street, the dyno, or the track — heat becomes your biggest enemy. The stock intercooler quickly reaches its threshold under higher boost, reducing power and engine efficiency.
That’s where the new CSF x Jackson Racing High-Performance Stepped-Core Intercooler for the Toyota GR Corolla and GR Yaris steps in. As the official distributor of CSF in the OEA, we welcome you to the ATOMIC-SHOP UAE to reach out this crucial upgrade. 
Developed for the most demanding Toyota builds, this is the largest “drop-in fit” intercooler available on the market — engineered for plug-and-play installation with minimal modification, yet capable of delivering real-world performance advantages under pressure.
Engineered for Maximum Performance
This intercooler is built around a stepped tube-and-fin core design, maximizing external surface area for heat dissipation and internal volume for superior airflow. Using 3D scanning and rapid prototyping, CSF has created a product that fits perfectly within the GR Corolla’s engine bay while dramatically enhancing cooling capacity.
Real-world testing by MotoIQ confirmed that the intercooler lowers intake air temperatures significantly compared to the OEM unit, improving charge density and reducing the risk of heat soak during repeated high-load situations.
Motorsport-Grade Build Quality
This isn’t just a cosmetic upgrade — it’s a race-proven solution:
- 100% TIG-welded aluminum construction for unmatched durability
- No plastic crimped end tanks like the OEM part
- Includes motorsport-grade silicone hoses and clamps
- Enlarged 2.5” (63.5 mm) inlet/outlet for better airflow
- Individually leak- and pressure-tested to ensure factory reliability
- Minor trimming of the OE ducting is required — no further modifications
Backed by a 2-year limited warranty, this intercooler is built to endure the rigors of street performance and track day abuse alike.
