K&S TECHNOLOGIES 1903-0008 58-1001 Standard-Pressure Radiator Cap Gold - 16 PSI 1.1 Bar

OVERVIEW

K&S TECHNOLOGIES engineered this standard-pressure radiator cap to maintain precise cooling system management during routine maintenance or cold-start rebuilds. Constructed with heavy-duty metal housing and fitted with high-temperature silicone internal seals, this 1.1 bar replacement secures reliable thermal regulation across Honda, Kawasaki, Suzuki, and Yamaha powersport platforms.

ENGINEERING & PERFORMANCE

The stamped 1.1 bar pressure rating ensures consistent coolant retention without premature valve venting, keeping engine operating temperatures stable under sustained load. Premium high-temperature silicone seals resist thermal degradation and swelling during extended heat cycles, maintaining a leak-free interface between the cap and fill neck. This direct-replacement design matches OEM geometry and factory spring tension, allowing straightforward installation on stock liquid-cooled engines without auxiliary fittings.

KEY FEATURES

WHY RIDERS CHOOSE THIS

Riders select this K&S TECHNOLOGIES radiator cap when they need predictable thermal control without upgrading to oversized performance parts. The high-temperature silicone seals stay flexible through repeated heat cycles, preventing the slow coolant loss that plagues worn OEM units while protecting against air intrusion into the cooling jacket. Because the cap matches factory spring rates and bore dimensions, it drops directly onto stock fill necks without modification. For daily trail riders and weekend competitors alike, this standardized 1.1 bar cap delivers proven sealing reliability that keeps liquid-cooled engines running cool season after season.
