great stock replacement 2 years ago
5out of 5stars

I was hesitant to get this after all the negative Mishimoto stuff not the forums. But this is a great replacement radiator. I have over 5K miles on it now and no issues. FYI the auto and manuals are the same part number. For the manuals you will need to get some vacuum caps to cap the transmission cooler lines; No Plugs provided.

Replacement on 06 WRX Limited with 215K Miles 2 years ago
5out of 5stars

This radiator is a perfect replacement for an OEM swap. Make sure you have a couple smaller hose clamps for the two little hoses on the top end; the hoses will slip off without them. Other than that this is another great product built by Mishimoto and sold by RSD. Blew the top seam of the OEM radiator driving to work on a Wednesday (had been expecting that for a while), ordered this online that morning at work with 2-day shipping, received it on Friday, installed that weekend under 2.5 hours. A big thank you to the people behind the curtain at RSD for their quick response and friendly demeanor.

  • Q: Mishimoto OEM radiator  MOMOTORSPORTS1 year ago

    Hi, does the radiator come with a cap? and does it matter what rating the plastic radiator uses compared to an all aluminum radiator?

      A:  No this will not come with a radiator cap, also yes it will matter. Obviously, you won't want to put this in a vehicle pushing 500+ HP.
