Absolutely Incredible! 2 years ago
Jared A.
This fit incredible well on my Focus ST, literally nothing had to be modified to fit. The one thing I did have to change out was the oil filter(Due to the thread pitch being different on the pin that holds the sandwich plate up) , I ended up just going with a oil filter off a 2012 STI. So far under aggressive driving the Oil temps stay low and the Oil pressure looks great. Aside from having to let my car warm up a little bit longer this oil cooler is a 10/10.

This is a high quality product with an easy install. Looks bad ass and keeps the oil temp down during track days.

QUESTIONS & ANSWERS

  • Q: Thermostatic Sandwhich Plate  JR1 year ago

    Will the "Mishimoto Oil Cooler Sandwich Plate Thermostatic - Universal MODEL # MIS MMOP-SPT Manufacturer Part # MMOP-SPT" fit with this? I live in a colder climate and hear I need this to prevent over cooling the oil.
    • 0 of 0 people found the following answer helpful

      A:  It has not been test fitted before but should not be an issue.

      A:  There is no need for a thermostat with an external oil cooler on the modern EJ engine. The factory oil/water heat exchanger will stop the oil temps getting too low.

  • Q: Horn  Bobsagget1 year ago

    One of the OEM horns is mounted in the same location as the core would seem to be. Does the horn have to be relocated? if so where? Also does the product come with installation instructions?
    • 0 of 0 people found the following answer helpful

      A:  You will need to either relocate or delete that horn. Yes this will come with instructions.

  • Q: Process West oil cooler  himvictor3 years ago

    Would this fit if my 2009 WRX STI hatch if it has a Cusco Power brace front member installed? Also is it bad to have this if I daily my car in California?
    • 0 of 0 people found the following answer helpful

      A:  We cannot confirm fitment with braces we have not tested. Colder climates typically will want a thermostatic sandwich adapter, but it is likely not needed for your area.

  • Q: Thermostat  kechup1473 years ago

    Is there a thermostat included with that kit ? Or does it not need a thermostat ? We have very cold winters in Canada so just want to make sure before I order haha, thanks!
    • 0 of 0 people found the following answer helpful

      A:  The sandwich plate adapter included with this kit does not have a thermostat, and we recommend a thermostatic adapter if you live in a cold climate or if you use your car for daily driving because over cooling the oil will not allow it to lubricate as intended.
