SUBARU WRX/STI X-LINE PERFORMANCE ALUMINUM RADIATOR

When properly maintained, the Subaru flat-four is well known for its substantial power and impressive reliability. Proper regulation of coolant temperature is key to extending the life of your EJ-powered Subaru. Highly modified turbocharger setups and aggressive driving can result in high temperatures, which increases wear on internal engine components. Mishimoto’s X-line aluminum radiator is engineered specifically for the 2001–2007 Subaru WRX/STI and features a large three-row core and full aluminum construction. This design yields optimal temperatures even in the most demanding environments. This radiator also features a 100% brazed aluminum core with TIG-welded end tanks for increased durability, longevity, and a substantial increase in coolant capacity. The large three-row core enhances surface contact, resulting in improved efficiency, improved heat transfer, and lower engine coolant temperatures for your Subaru.

The Mishimoto Subaru WRX/STI radiator includes a Mishimoto 1.3 Bar High-Pressure Radiator Cap, which effectively raises the boiling point of coolant to create a safer and more efficient system. Included with this radiator is a Mishimoto M16 Magnetic Oil Drain Plug that removes metal fragments circulating in the coolant system, thus further protecting your engine. Whether you are looking for a reliable stock replacement radiator or a heat exchanger efficient enough for track abuse, the Mishimoto Subaru WRX/STI X-line Performance Aluminum Radiator is an ideal choice. As with all our products, this aluminum radiator is backed by the Mishimoto Lifetime Warranty.

Features

  • Large three-row aluminum core provides additional coolant capacity, substantial coolant surface contact, and optimal coolant temperatures even in the most demanding environments
  • Industry-largest 2 inch thick core for ultimate cooling efficiency
  • Full aluminum construction for increased durability

NOTES

The provided Mishimoto radiator cap should replace the stock cap located on the expansion tank. The stock cap attached to the radiator should be installed on the Mishimoto Performance Aluminum Radiator. The Mishimoto radiator cap is a two way valve, while the stock radiator cap is a single valve. Due to the difference in construction, the Mishimoto cap cannot be used on the radiator. If the Mishimoto cap is fit on the radiator, overheating may occur.

Due to the additional thickness of our 3-row X-Line radiator, trimming the upper hose may be necessary.

For 2002-2003 Subaru WRX models built before 7/2002, remove fill neck overflow nipple and replace with 1.5875mm NPT plug provided.

Mishimoto X-Line Radiator | 2004 SUBARU STi

Received it looking top notch and works great fitting is good also but you just gotta trim you hoes a little to fit because of the radiator fan is right next to it. Trim the hoes so it'll be shorter and not in the radiator fan ways so it can spin freely with no contact!

Easy to install. Mishimoto radiator hoses will have to be trimmed both top and bottom. Noticed difference instantly and it changes from hot to cold in seconds. Only downfall i would say is i wish it came with 2 new caps instead of 1 as the cap that comes with it is for the expansion tank, otherwise great product!!!
