Reische Performance FORD-4S 170° Performance Thermostat

*image is only a representation and may not be accurate

This premium thermostat has a larger heat motor/spring assembly for more precise temperature control along with a heavy gauge chrome plated steel housing. 100% made in the USA.

Beware of aftermarket companies who sell the same thermostat for all Ford modular engines. Reische Performance thermostats are the only ones designed to precisely fit each application, making them the best performing low temp units on the market! Whether you are using an aftermarket radiator or not, this thermostat will provide the best possible heat dissipation from your setup along with a faster warm up time and better cold weather performance than a 160° unit or a thermostat with holes drilled in the diaphragm. We believe the 170° opening temp is the ideal balance for high performance engines, providing high flow to your radiator by mid-180 temps while still providing good all season performance. With proper fan settings your coolant temps in cool weather will be in the 170s and in hot weather the 180s, giving those running high levels of timing and/or boost added protection against engine-damaging detonation as well as maximum power output.

For 4.6/5.4/6.2/6.8L SOHC, including 2007-2010 Mustang GT & 1996-2004 Mustang GT. All Reische Performance thermostats ship with a new o-ring, recommended fan settings for popular handheld programmers and are backed by a 5 YEAR WARRANTY.

Customer Reviews

High quality parts and service. Review by Rothe
A high quality part that was very easy to install. Total installation time is about an hour and a half. My car runs cooler and I don't have to worry about it over heating on hot summer days. (Posted on 5/19/15)
Unboxing Review Review by Rothe
I ordered this thermostat on Sunday the 18th and initially the tracking number said that it wouldn't be here until Saturday the 24th. I walked out to get the mail today after work and it was here. Upon removing it from the box get a very high quality looking piece. I was surprised at the quality actually. I haven't installed it yet, and hopefully ill get to later this weekend. After I install it I'll update this review. (Posted on 5/22/14)
