Features & Product Details

RallySport Direct carries a large selection of the Mishimoto Performance Aluminum Radiator to not only improve the cooling efficiency of your vehicle but to also make for an excellent upgrade over your factory unit.

Here are the key features:

  • Full aluminum construction provides increased heat and pressure tolerance, improved heat dissipation, increased durability and improved cooling efficiency
  • Manufactured with TIG-welded end tanks for improved strength and extended service
  • 100% brazed aluminum core for maximum reliability
  • Increased coolant capacity directly results in improved cooling efficiency
  • Included 1.3 BAR radiator cap raises the boiling point of engine coolant to provide a safer and more efficient system
  • Designed to original equipment specifications
  • Designed for manual transmission models
  • Please note: The radiator cap provided with this particular radiator should replace the stock cap that is located n the expansion tank. Your factory issued/stock radiator cap should be the one used on the Mishimoto Radiator. The Mishimoto radiator cap is a two-way valve, and when compared to the stock single valve, there is a difference in construction, and cannot be used on the radiator. If you try to use the provided Mishimoto cap on the radiator, then you risk overheating.

    Great radiator, low temps, hold more coolant 2 months ago
    5out of 5stars

    Works great on the track, temps always pegged at 185F even on 90F+ track days. Been working great for over a year now. Install is tricky and upper hose clearances required extra cutting/fitting work. Standard burping procedure w/ an overflow funnel doesn't work as air gets trapped on the drivers side upper section of the radiator and you have to turn off the car and open up the radiator cap slightly to let the air drain as it is unable to flow into the passenger side reservoir (must be super careful doing this not to get burned or allow coolant to flow out of the top)

    Good radiator from Mishimoto. Had to trim some hoses to fit, including lower and upper radiator hoses, and the hoses from the expansion tank.

    It takes work.  7 months ago
    4out of 5stars

    After partially installing the radiator I realized I needed to alter the two upper radiator mounts. The radiator leans towards the engine which makes it almost impossible to connect the small hose from the upper reservoir to the small hardline that runs across the radiator. I had to grind tabs off the stock radiator mounts and file the holes deeper with a round file. This allowed the radiator to sit more flush with the front of the car and give just enough clearance to connect the small hose. I had to cut both the hoses coming off the upper reservoir shorter, cut the upper radiator hose 1 inch shorter (radiator side) and cut the lower radiator hose 1 inch shorter (engine side). Then my stock cap did not want to fit (as recommended by Mishimoto) and took a lot of effort to get it on. Soooooo, my point is maybe consider something else if you aren’t comfortable with making serval adjustments. Also, it takes about 2 gallons of coolant for anyone wondering. Can judge performance yet because i didn’t have 2 gallons of coolant.

    This radiator has been great for 3 years. Living in Atlanta, it gets and stays pretty hot. Never had an overheating issue. Great price too.

    Looks fantastic and hopefully won't spring a leak like my stock one did. Some fantastic looking welds.

    QUESTIONS & ANSWERS

    • Q: Mishsi Performance vs. Xline  Kwiksti6 months ago

      What is the difference between this and there X-Line radiator for the STI?
    • Q: Fitment: Will a killerbees dual tank clear?  JF8 months ago

      Will this with the killerbees dual tank clear the air pump on a 2012 WRX?
      • 1 of 1 people found the following answer helpful

        A:  This has not been test-fitted with the killer B Dual tank so we cannot confirm that it will clear. To give you an idea for size comparison, this radiator is about 0.9 inches deeper than the stock radiator depth.
