    hose kit replaces aging Samco upper and lower 2 years ago

    Installed this upper and lower hose kit when the OEM radiator was replaced due to a leak from the upper tank. The hoses were a perfect fitment using the supplied worm gear clamps, no trimming necessary with stock or OEM replacement radiator on 2002 manual transmission WRX. I suggest installing the lower hose onto the new radiator and matching the way the hose is angled on the old radiator before dropping the new radiator assembly into the car. It's a lot easier than trying to tighten the clamp with the radiator already in the car (although it can be done).

    Hoses need to be trimmed. 2 years ago
    3out of 5stars
    These look like they'd be a direct replacement for individuals running OE radiators. However, if you have a thicker aftermarket radiator, you'll need to trim about half an inch off the top hose(rubs on pulleys), and about 3/4 inch off the bottom hose(It'll be slightly kinked if you don't).

    I've had these on the car for several months now. So far, I've had no issues with them. I bought them when Mishimoto was doing a large sale so I couldn't pass up the deal.

    great product and great company  7 years ago

    I've run these on my car for over year and have been pleased with them. They do look go in the engine bay. I did upgrade my radiator this past weekend and made the mistake of over trimming the top hose and causing it to contact the P/S pulley, it was my mistake, just got carried away with the razor blade. I contacted mishimoto to see if I could just buy the top hose. I was shocked to find out that they were going to send me a complete set, with these trick not cut clamps at a very good price. What a great company to help their customer out on a problem that wasn't their fault. I will buy their products again.

    Came Loose 7 years ago
    4out of 5stars
    These hoses look awesome with the engine, and hold up to all the pressures of pushing the car at auto-x. Be sure to buy good, snug hose clamps though! My lower hose came loose and resulted in the car nearly overheating many miles from home.

    • Q: 2015 STI   Tarek6 years ago

      does these hoses fit the Mishimoto Performance Aluminum Radiator X-Line Manual Transmission on my STI 2015?
      • 0 of 0 people found the following answer helpful

        A:  These hoses are not confirmed for the 2015 STI. Unfortunately we do not have a confirmed option from Mishimoto for radiator hoses at this time.
