Mr. Gasket 4364 High Flow Thermostat - 180 Degrees

High Performance cooling with reliable flow

The Mr. Gasket 4364 High Performance/High Flow Thermostat opens at 180 degrees to help regulate engine temperatures under demanding driving. Built to tolerate large variations in coolant pressure at high RPM, this unit aims to deliver a steady, predictable flow through the cooling path. Its copper and brass construction resists corrosion, giving you a durable component that stands up to the elements under daily driving and track sessions alike.

Designed to fully open at the correct temperature consistently, regardless of engine RPM, the 4364 supports a stable cooling curve as the engine works harder. This feature is especially valuable for enthusiasts who push their vehicles on the street, at the drag strip, or on oval tracks where heat and load can change quickly. The result is a thermostat you can rely on when the goal is maintaining coolant movement without abrupt temperature swings.

Key benefits you can count on

• Opens at 180 degrees to help manage engine temperatures during spirited driving
• Resists large variations in coolant pressure at high RPM for consistent performance
• Fully opens at the target temperature no matter the engine load
• Suitable for high performance street, drag racing, and oval track applications
• Copper and brass construction resists corrosion for longer service life

In real world use, you might notice a smooth, steady cooling response as your engine warms and then maintains a stable temperature under load. The 4364 is designed to work within typical performance cooling systems, offering a predictable opening point and reliable operation when a vehicle is pushed beyond casual cruising.

Practical notes for installation and care

• Easy swap-in design that matches common high performance cooling setups
• Works with standard housings and gaskets used in modified street and race builds

To maximize longevity, keep the cooling system clean and inspect for signs of scale or corrosion during routine maintenance. While not a guarantee of increased speed or power, many users appreciate the consistent opening at 180 degrees and the durable copper-brass construction in demanding conditions.
