Mugen Radiator Cap - 19045-XGER-0000

This cap is designed to run a slightly higher relief pressure than typical OEM-style caps, helping the cooling system stay more stable when temps start to climb. It’s a smart upgrade for spirited driving or warm climates, with a heat-resistant silicone seal for consistent sealing.

• Part #: 19045-XGER-0000
