While the foundation of Hypertech's business is in electronics and engine management software, the accessories the company offers are of the same high quality. Hypertech understands the importance of temperature regulation when it comes to performance engines. That is why the company offers its Hypertech Thermostats. After you have made a number of upgrades to your vehicle, it should put out a significantly greater amount of power. However, with more power comes more heat released from the engine, as heat is a natural byproduct of combustion engines. The problem is that engines need cooler air to burn fuel more effectively. Hypertech Thermostats are designed to be upgrades over your old factory thermostat, which was not intended to handle your tuned ride's extra power. Hypertech Thermostats were designed to help keep your engine area at an ideal temperature for combustion and to keep fuel from burning prematurely, which happens when engine bays get too hot. This is a condition known as "knock" and can do severe and irreparable damage to your engine if allowed to go on over a long time. Besides thermostats, Hypertech also offers a number of accessories for fuel delivery systems, spacer kits, ignition coils and distributor caps.
