KOSO High-Flow Fuel Injector for Honda Grom & Monkey – DB008160

KOSO North America High-Flow Fuel Injector – DB008160

Unlock the full potential of your Big Bore build. The KOSO DB008160 High-Flow Fuel Injector is engineered specifically for Honda Grom and Monkey riders running 150cc or 170cc Big Bore kits and 4-valve head upgrades. By delivering precisely metered fuel into an enlarged combustion chamber, this injector ensures your engine breathes and burns at peak efficiency — no lean spots, no hesitation, just clean power.

Designed to pair seamlessly with the Koso intake manifold, the 160cc flow rate matches the increased displacement demand of your upgraded motor. It's a small component with a big impact — the missing link between your Big Bore kit and the performance gains you're chasing.
