Billet aluminum boost box for the G43L engine (GSR40, GSR40-TS, and Go-Bike) from ADA. Improves throttle response, acceleration, and overall performance. ADA testing showed a 1.2mph top speed gain. Reduces intake noise. Works with stock GSR40 carb, GSR40-TS stock carb (Walbro WYK-33), and ADA GSR HP carb (WYK-58). Carb mounts directly to boost box - no additional intake manifold required!
Walbro WA or WT (TGN GSR HP Carb) butterfly style carbs require adapter (sold separately, part AV226). Note: Juice Box installation requires trimming of the plastic engine shroud.
