BLOX Racing 88-91 Honda Civic Type-A Radiator Cap - 1.3 Bar

This BLOX Racing radiator cap is set to open at 1.3 Bar (18.8 PSI), which is higher than the stock pressure for many vehicles. Raising the pressure at which your radiator cap opens allows your coolant to reach a higher temperature before it starts to boil. This can help prevent overheating, especially in demanding driving conditions or when your cooling system is under stress.

Crafted with durable materials, this cap is built to handle the increased pressure and temperature cycles within your cooling system. It's a straightforward replacement for your old, worn-out cap, and a simple way to ensure your cooling system is operating at its intended pressure. If you're looking to get the most out of your cooling system, especially if you've made other modifications, a higher-pressure cap like this one is a solid choice.
