Installing Mishimoto X-Line Radiator | Subaru WRX STI Cooling Upgrade

In this video, I install the Mishimoto X-Line Radiator on my Subaru WRX STI — a serious cooling system upgrade built for performance and reliability. Whether you’re tracking the car, running high boost, or just want to protect your EJ motor, this is a must-do mod.

✅ What you’ll see:
• Step-by-step Mishimoto radiator install
• Fan shroud + coolant tips
• First start-up and burping the system
• Why upgraded cooling is critical for WRX/STIs

This is one of those mods that pays off long-term. Cooler temps = better performance and more peace of mind.
