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 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 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 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 radiator is backed by the Mishimoto Lifetime Warranty.

    Great quality and performance
    Size: 1" x 1" x 1"
    The quality of the filter is great and it is easy to installed in your car. Also, it helps to improve the performance of your vehicle, keep clean air flowing and avoid bad smells. What I love about it it’s the option to washed it and reuse it over an over.

    Awesome product!
    Size: 1" x 1" x 1"
    Awesome product! Fit just as it should. A lot better then buying the replacement ones every time I do an oil change. I drive a mile of gravel roads everyday and this helps keep the dust from coming into the vehicle.

    Fit my Subaru Forester perfectly!
    This fit my 2024 Subaru Forester perfectly. The filters exhibited a high quality construction and was packaged well. Installation was easy and saved me a lot of $ vs. having my dealer install an OEM filter.
