A lot of motorists out there have learned the hard way that uncorking a hot radiator causes the coolant inside to boil over like a science fair volcano. Trouble is, you can't really know for sure just how hot your system truly is by looking at it—until now. The Mishimoto Temperature Gauge Radiator Cap comes with a precision temp gauge built right in, so you can check the conditions under the cap at a glance.
Whether you're working in the pits or topping off your antifreeze at the gas station, the Mishimoto Temperature Gauge Cap gives you invaluable insight into your cooling system even if you don't have an in-cab temperature gauge. But, that's just the tip of the iceberg. These race-ready radiator caps are engineered to withstand up to 1.3 bar (19 lbs) of pressure—far more than stock caps. Beyond the bragging rights, that strength helps hold a tighter seal to stop your coolant from bubbling up and spilling into your overflow reservoir.
Custom designed for your exact year, make and model, the Mishimoto Temp Gauge Radiator Cap mounts with a simple twist and adds an electrifying new look under your hood. They're available for a wide range of Detroit-born and imported autos, and they all come with a Lifetime Warranty.
