OEM E-Z-GO / Cushman Throttle Body Assembly
For Kawasaki 13.5-HP EFI Engines (2019–2025)**
Give your golf cart the performance it was built for. This genuine OEM E-Z-GO/Cushman/Walbro throttle body assembly restores factory power, smooth acceleration, and reliable EFI performance on vehicles equipped with the 658237 Kawasaki 13.5-hp fuel-injected engine.
