Mishimoto 2004-2008 Subaru Forester XT (Manual Only - Not For A/T)

This Mishimoto performance aluminum radiator is a direct-fit upgrade for 2004-2008 Subaru applications covering Forester XT. It replaces the weak points of the stock part with stronger materials and better flow or cooling so heat, boost and abuse stay under control on street and track duty. AutoTalent lists verified US-market fitment in the table below.

Why upgrade

Keeping your turbocharged Forester XT cool is essential to maintaining performance and reliability, whether you’re navigating rush-hour traffic or exploring winding back roads. The factory radiator can struggle to keep up with the heat generated by the 2.5L turbo engine, especially under heavy loads or in warm weather. These kits are engineered around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it.

Features

• Two-row, 1.65-inch thick efficient brazed aluminum core provides ideal fluid temperature reduction — engineered for the turbocharged Forester XT on the street, track, and rallycross course.
• Increased fluid capacity and superior heat dissipation over the factory unit give the Forester XT more thermal headroom during repeated heat cycles.
• Two 1.3 bar high-pressure caps, two-way expansion tank cap, one-way radiator cap, and Magnetic Drain Plug included — a complete cooling system install with no missing hardware.
• Full aluminum construction with TIG-welded end tanks eliminates the failure-prone stock plastic end-tank radiator that cracks under boost pressure and heat cycling.
• Two-row brazed aluminum core with 1.65-inch thickness efficiently moves heat into the airstream, sustaining stable outlet temperatures during back-to-back runs.
• Confirmed direct fit for the 2004–2008 Subaru Forester XT — no cutting, fabricating, or adapter work required.
• Handles the cooling demands of stock and modified Forester XT builds, including stage-tuned and high-boost setups running street, track, or rallycross duty.
