Mitsubishi Evo X (CZ4A) Radiator & Cooling FAQ's

Please read our FAQs page to find out more.

Will an aluminum radiator help my Evo X on track?

Yes. Thicker aluminum cores increase capacity and reduce heat soak. Pair with shrouded fans and ducting for best results.

Is an oil cooler necessary for a tuned Evo X?

For repeated high-load driving, a thermostatic oil cooler keeps temps in check. Route lines away from the downpipe and shield with heat sleeves.

How do I cure intercooler heat-soak in the Evo X?

Seal shrouds, improve airflow, and keep the condenser clean. A more efficient FMIC core with better end tanks lowers IATs.
