Product Details

The Mishimoto MMTS-WRX-01 racing thermostat is engineered to optimize cooling performance in 2001-2014 Subaru WRX and 2001-2021 STI models. This performance thermostat opens at a lower temperature than the factory unit, allowing coolant to flow through the engine sooner and maintain more consistent operating temperatures.

Key Features:

  • Lower activation temperature promotes increased cooling efficiency throughout the engine
  • Helps manage higher heat loads from modified and turbocharged applications
  • Allows coolant circulation at an earlier point in the warm-up cycle
  • Reduces peak engine temperatures during high-performance driving
  • Direct fit replacement for OEM thermostat
  • Mishimoto Lifetime Warranty included

This racing thermostat is an essential upgrade for WRX and STI owners running increased boost, aggressive tunes, or track applications where managing engine temperatures is critical for performance and reliability.

Easy ordering. Best price!

Easy to find products quick checkouts and invoices from your order

thanks

great pricing and fast shipping

My initial review was 1 star because I ordered a Thule rooftop cargo box, but cancelled the order after Autoplicity called me about collecting extra money to ship the item after their website did not charge me enough for shipping. After my initial review Autoplicity offered to ship the item totally free since the issue was a flaw in their website. This was unexpected, above and beyond in my opinion. I have yet to receive the item but commend Autoplicity's customer service

Fast Shipping, Great price, Parts were well packed

I was looking to buy a gale banks header for my jeep. I came across this site th eir price was nearly $100 cheaper than any one else. Fast shipping too. Thank you.

Did not receive a confirmation email when I placed the order so I was unsure if if the order had gone through properly. Part shipped the day after I ordered it. I received three confirmation emails at the that time for some reason. Overall I would say the experience ordering from Autoplicity was excellent and inspired confidence.

Product arrived fast and as described. The best price I found online. Packing was excellent, highly recommend Autoplicity.

Great Company. I needed a part quickly and for the right price. They had the best price on the internet, and made sure it got to me in two days before I went away on my road trip. I spoke to a representative that was very helpful. I highly recommend Autoplicity! Thanks!!!

Great site! Just what I wanted!
