Alliage Nitro Engine Tube de pression négative Heat Sink (Ø12 * 63mm)
cool! i like holder includingmy nitro MT has so much pressure return on the tank that it creates bubbles in my fuel line. with this I can control that a little. its not easy to tune this but it is worth it. I don't know about cooling... I can't place it on the wind to reduce any heat but it should work. the fins are very big, the air is just not easy to cool down.Muy util en competencia,me permite lograr una mejor carburacion y reducir la temperatura de el tanque de combustible.this thing help you regulate the backpressure air from the exchaust into the feul tank into the motor it cools the air leading your engine to run on lower temp increasing engine life....
