Honda CRF 250/450R 2nd Injector Airbox Kit

A second injector delivers significantly sharper throttle response along with a more aggressive and powerful power delivery throughout the entire rev range. Working in combination with the stock injector, the system is engineered to elevate overall performance, power output, and riding feel to the next level.

The LWR 2nd Injector Kit features a high-quality two-piece velocity stack manufactured using industrial-grade 3D printing technology, combined with a CNC-machined fuel line adapter. This design ensures maximum durability and a dust-proof seal of the airbox, developed specifically for the highest demands of racing conditions.

Each kit is carefully hand-assembled and delivered in a genuine Honda OEM airbox. The package includes the injector, wiring harness, velocity stack, fuel line, and all necessary mounting hardware for a true plug-and-play installation.
