not for bis...
I will try write it my self....
its piece under the carburator, its 70mm high and petrol is better mixed. have "fan" inside and that mixing petrol with air much better.... some people say car is bit stronger, some say its piece of poo.... after 10k that "fan" will broke and you have to take it off there is little net to catch it... some racers in poland use it without that "fan" to lift carburator... I newer drived with it-cant say ist good or bad....
sorry for english keep learning
