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.
