Tech Insight

A 160° thermostat is commonly used in performance and off-road builds where lower operating temperatures are preferred, especially in:

  • High compression engines
  • Forced induction setups
  • Slow speed rock crawling applications
  • Heavy load towing or trail rigs

Proper thermostat selection helps maintain stable engine temps, especially in builds where airflow is limited or under heavy load conditions.
