Product Details

The Mishimoto MMTS-240-89KA Racing Thermostat is engineered to provide optimal cooling performance for your Nissan 240SX. This low-temperature thermostat is designed to open at a lower temperature than the factory unit, allowing coolant to flow through the system earlier and helping maintain cooler engine operating temperatures during aggressive driving conditions.

Key Features:

  • Lower activation temperature for improved cooling efficiency
  • Direct replacement for OEM thermostat
  • Compatible with KA24DE and SR20DET engines
  • Precision-engineered for reliable performance
  • Backed by Mishimoto Lifetime Warranty

Fitment:

  • 1989-1998 Nissan 240SX with KA engine
  • 1989-1998 Nissan 240SX with SR20 engine swap

Ideal for track use, spirited driving, or turbocharged applications where maintaining optimal engine temperatures is critical. This racing thermostat helps reduce the risk of heat-related engine issues while maximizing performance potential.

Good price

ordered a wagner lamp cabinet, it arrived as described in a timely manner.

Speedy and easy service

quick and easy

Autoplicity had the parts in stock when no one else did. Shipment received within a few days. This was my first purchase from Autoplicity and would certainly buy from them again.

It was okay. Shipping was expensive w/o discount.

great pricing and fast shipping

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.

Great product, Vette window louver. Install went well. (take your time, follow instructions to the letter). Look great on the car.

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