The Mishimoto BMW S55 motorsport thermostat for the BMW M2/M3/M4 2015-2019 is designed to help your cooling system operate at peak efficiency, whether you’re cruising to your local car meet or tearing up the track. Our thermostat begins to open 9°F (5°C) earlier than the stock thermostat at 212°F (100°C). That allows precious coolant to flow into the radiator and start shedding heat sooner. Couple this thermostat with a Mishimoto performance aluminium radiator and you have the recipe for an engine that runs cool no matter the situation. This thermostat includes an OEM-quality housing and like all of our thermostats, this BMW M3/M4 2015-2019 thermostat is backed by our Mishimoto Lifetime Warranty.

PREPREG is a common term for a reinforcing fabric such carbon which has been pre-impregnated with a resin system. This resin system (typically epoxy) already includes the proper curing agent. As a result, the prepreg is ready to be laid into the mold without the addition of any more resin. In order for the laminate to cure, an autoclave production process is used, a combination of high pressure and heat.
- Maximum strength and performance characterictics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content. Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination.
- Uniformity and repeatability. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same. Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency.
- Reduce curing time. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured.
- Aesthetics. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
