NCY Performance Bolt-On Oil Cooler Kit | GY6, Genuine

Maximum Cooling, Easy Installation

Protect your investment and unlock consistent power with the NCY Performance Oil Cooler Kit. Engineered for high-output 125cc–170cc engines, this kit is the definitive solution for riders facing high ambient temperatures or running aggressive Big Bore setups. By circulating engine oil through a high-efficiency aluminum radiator, this system significantly reduces operating temperatures, prevents thermal breakdown of your oil, and ensures your engine maintains peak horsepower during extended wide-open-throttle runs.

Advanced Thermal Engineering

• High-Efficiency Aluminum Radiator: Dense fin-and-tube design maximizes heat exchange and keeps oil within the optimal temperature range.
• Durable Silicone Oil Lines: Includes 4.25 feet of premium silicone hosing rated for 300 PSI — superior heat resistance and flexibility vs. standard rubber lines.
• No-Mod Adaptation Kit: Precision-machined M30x1.5mm aluminum-alloy drain banjo adapter for a leak-free connection with no engine modifications required.
• Complete Hardware: Stainless steel banjo bolts, copper crush washers, and a specialized adapter spanner wrench for a professional, secure setup.

Tuning Note: Lower oil temperatures mean longer engine life. This kit is essential for engines with 160cc+ Big Bore kits to prevent overheating. Mount the radiator in a high-airflow area away from the exhaust for maximum cooling efficiency. Check your oil level after the first few miles — the cooler and lines hold a small additional volume of oil.
