Whether you daily drive a stock STI or rallycross a modified WRX, an efficient cooling system is key to extending the life of your flat-four. The plastic end tanks of the stock radiator are especially prone to cracking from years of constant variation in temperature. A radiator failure can result in overheating, head gasket failure, and other engine damage that can quickly put an end to a fun day at the track. Protect your investment with the Mishimoto performance radiator engineered specifically for the 2001-2007 Subaru WRX/STI. After identifying the radiator in these vehicles as a weak point, our engineers set out to provide an efficient, durable radiator that can take the abuse of competitive driving and provide the reliability you need for daily commuting.
The Mishimoto Subaru radiator features all-aluminum construction, which provides increased heat and pressure tolerance, improved heat dissipation, and improved cooling efficiency. The 100% brazed aluminum core and TIG-welded end tanks provide optimal durability and years of efficient and reliable service. This radiator is a complete bolt-in unit and replaces the factory radiator without requiring any modification to your Subaru. The Mishimoto Subaru Performance Aluminum Radiator includes a Mishimoto 1.3 Bar High-Pressure Radiator Cap. This cap effectively raises the boiling point of the coolant, thus providing a higher threshold for safe temperatures and resulting in a more efficient cooling system. This radiator provides a significant increase in coolant capacity, which allows for aggressive driving while retaining safe coolant temperatures. Keep your Subaru on the street and out of the shop with the Mishimoto Subaru WRX and STI Performance Aluminum Radiator. As with all our products, this radiator includes the Mishimoto Lifetime Warranty. For additional technical information, contact sales@mishimoto.com

Stock OEM Radiator vs Performance Aluminum Radiator:
A stock radiator may be fine for your grandmother who drives 25 mph to the grocery store once a week, but for those of us who can never have enough power a high-performance cooling system is a must!
Even if you don't put a beating on your car everyday, we all have that urge to push our cars to their maximum ability. A blown motor is the last thing anyone wants to deal with. After all, you deserve to be able to push your car to the limits! High-quality, reliable cooling products are essential if you want to enhance the lifetime and performance of your vehicle, while at the same time preventing engine failure.

The Engine:
A car's engine has tons of moving components. As these parts move they create friction, which creates heat. Motor oil is pumped through the engine block to assist in lubricating these moving parts; however, motor oil is not enough to beat the heat! As a normal result of a working engine, the parts become boiling hot.
If you have that need for speed and are running an upgraded or modified engine, you will need to upgrade your cooling system as well. Stock radiators can't handle the heat produced by these types of engines. The more horsepower your engine puts out, the more heat it produces. The engine block must be kept cool to avoid overheating and/or seizures. If the pistons cannot slide freely in their cylinders due to the excessive heat caused by friction, they will eventually snap and cause total engine failure.

The Radiator:
The radiator plays the most important role in maintaining a cool, efficiently running engine while preventing overheating. A mixture of water and antifreeze is pumped through the chambers in the engine block, and when this extremely hot engine coolant exits the engine block it goes straight to the radiator through the hose kit. As the hot coolant makes its way through all the chambers, fins, and tubes of the racing radiator, the extremely hot engine fluid is now cool enough to return to the engine block. This is a continuous process and the most effective way to keep your engine cool and running at its best. Aluminum radiators are the strongest and most durable. They can withstand the extreme conditions of everyday driving and are also much lighter than stock OEM radiators.
