MR. Gasket Thermocap - Radiator Cap with Built-in Temperature Gauge

Real-time coolant temperature, no wiring, no ECU, no guesswork.

• ▸Replaces your standard cap — reads temp instantly between sessions
• ▸Zero wiring required, fits Japanese-style radiator caps universally
• ▸Know your temps before damage happens, not after the light comes on

A dashboard warning light means the engine's already in trouble. The Thermocap shows actual coolant temperature at a glance, right on the radiator cap, before you pull back onto the pitlane. For Excel racers and budget builds running no factory gauges, it's the most practical cooling check you can add for the money.
