The Mishimoto racing thermostat for the 99-05 Volkwagen GTI 1.8T will promote greater cooling efficiency in your stock or modified GTI. Once the engine is fully warmed up, Mishimoto's Volkswagen GTI racing thermostat will open at a lower temperature than standard thermostats. This allows coolant to flow through the engine sooner, which reduces and maintains cooler engine temperatures. The Mishimoto 99-05 Volkwagen GTI 1.8T racing thermostat is the perfect addition to your street or track GTI and is a direct replacement for the stock thermostat. This thermostat includes the signature Mishimoto Lifetime Warranty.Engine coolant thermostat designed to regulate coolant flow and maintain optimal operating temperature. Ensures efficient warm-up, prevents overheating, and supports reliable performance with a precise fit.

Lower activation temperature allows coolant to flow through the engine earlier, maintaining lower temperatures (Mishimoto thermostat activates at 180F vs. stock 188.6F)
