Lingenfelter 174º Thermostat

Level 7 Motorsports

Regular price $35.95

Lingenfelter Performance Engineering offers premium-quality thermostats for several applications. They're all direct drop-ins with no modifications needed and each includes the rubber seal. Reduce coolant temperature, produce more horsepower, and improve performance with Lingenfelter Performance Engineering thermostats.

Level 7 has been using this specific thermostat in our builds for the past 8 years.  We prefer coolant to start cycling and equalize temperature for better electric cooling fan operation.  We have found that people make the mistake of turning their cooling fans on at 195-198º while the factory thermostat has just started to open at 192-194º.  When returning cold water will force the thermostat to try and close again.
