Evomx fuel tank foam is the latest technology in foam for your fuel tank. Evomx foam has been race proven to be one of the latest accessories to improve handling and track performance for any watercraft, dirt or street motorcycle and atv. Evomx foam is military spec foam that contains thousands of pores which eliminates sudden and violent sloshing of fuel within the tank. These effects are mostly felt in tight turns, breaking bumps, and G-outs. This is where your 12-15 lbs. of fuel can feel more like 25-30 lbs. sloshing front to back and side to side. With the fuel being stabilized from the Evomx foam in your watercraft, dirt or street motorcycle and atv tank you can experience your vehicle feeling 15-20 lbs. lighter. The foam is also so porous that it only takes 1 % of the volume of the tank and also has a 15 year lifetime.
