Radiator Mishimoto for Subaru WRX and STI / 01-07 / 3 Row
721 x 437 x 63,5mm
Well-maintained, the four-cylinder of the Subaru 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 turbocharged setups and an active driving style can lead to high temperatures that increase wear on internal engine components. Mishimoto's X-Line aluminum radiator is specifically designed for the Subaru WRX/STI 2001-2007 and features a large three-row core and complete aluminum construction. This design delivers optimal temperatures even in the most demanding environments and conditions. This radiator also features a 100% fully bonded aluminum core with TIG-welded end tanks for enhanced durability, longevity, and a significant increase in coolant capacity. The large three-row core increases surface contact, resulting in improved efficiency, enhanced heat transfer, and lower engine coolant temperatures for your Subaru.
The Mishimoto Subaru WRX/STI radiator includes a 1.3bar Mishimoto high-pressure radiator cap that effectively raises the boiling point of the coolant to create a safer and more efficient system. This radiator includes a Mishimoto M16 magnetic drain plug that collects metallic debris circulating in the cooling system, protecting your engine. Whether you are looking for a reliable replacement radiator for your stock unit or a radiator efficient enough to handle track demands, the Mishimoto Subaru WRX/STI X-Line radiator is the ideal choice.
Note: This product is for vehicles with manual transmission. Please purchase the Mishimoto universal radiator kit for vehicles with automatic transmission. Due to the increased width of the three-row X-Line radiator, it may be necessary to trim the upper hose slightly.
For Subaru WRX models from 2002-2003 built before 7/2002, remove the overflow nipple from the filler neck and replace it with the included NPT plug.
Radiator Cap:
The included Mishimoto radiator cap is not intended to replace the OEM cap on the radiator. The Mishimoto radiator cap is a two-way valve, while the OEM radiator cap is a one-way valve. Due to this design difference, the Mishimoto radiator cap cannot be used with this radiator. Using the Mishimoto radiator cap with the radiator may cause overheating.
Attention:
It is the responsibility of the installer to check all thermostat connections, NPT connections, line fittings, and other connections to ensure they are fully tightened before the vehicle is used. Mishimoto recommends checking all connections at regular intervals, especially after the first few kilometers following installation. Please contact us for further technical inquiries.
