OEM E-Z-GO / Kawasaki FJ400D EFI Engine (Closed-Loop EFI)
For 2019–2025 E-Z-GO & Cushman EFI Models
Bring your vehicle back to full factory performance with the genuine OEM E-Z-GO/Kawasaki FJ400D EFI Engine—the exact engine used in many modern E-Z-GO and Cushman EFI golf carts and utility vehicles. Built for reliability, smooth throttle response, and long-term durability, this closed-loop EFI engine is the premium replacement for worn or failed factory motors
.
Why This Engine Stands Out
- OEM Factory Engine – Not aftermarket. This is the real E-Z-GO/Kawasaki FJ400D EFI engine used on production lines.
- Closed-Loop Electronic Fuel Injection (EFI) – Delivers cleaner starts, better fuel efficiency, and consistent power in all temperatures and elevations.
- 401cc / 24.47 cu-in Single-Cylinder OHV – Proven, long-run reliability for work, play, or commercial use.
- Includes: Full engine assembly with throttle body and ignition coil
- Does NOT include: Dipstick, clutch, exhaust, starter/generator, or wiring harness (re-use your existing components)
- Designed specifically for EFI E-Z-GO & Cushman models (does not fit carbureted or Kymco EX1 units).
