H2O-STOP FUEL FILTER FOR GASGAS, HUSQVARNA AND KTM TOTAL FUEL SYSTEM PROTECTION

The problem

Every drop of water and every micro-impurity in gasoline reduces performance, increases consumption, and accelerates engine wear, especially in high-performance and off-road motorcycles like GasGas, Husqvarna, and KTM.

The solution

12 micron real filtration: blocks fine particles before they enter the fuel system.
Locks in water: retains up to 100 ml per fill-up of gasoline.
More kilometers with less consumption: cleaner and more efficient combustion even under demanding conditions.
Maintenance-free: up to 50,000 km or 2 years of worry-free use.
Install and forget: it mounts in minutes directly from the pond plug.

H2O-Stop PRO protects your GasGas, Husqvarna or KTM engine, prolongs the life of the fuel pump and helps you save fuel on every ride.

Frequently Asked Questions

Will it work if I already have an OEM filter?
Yes. The original filter works after the pond; H2O-Stop works before, inside the tank, separating the free water.

Does it work with E5/E10 gasoline?
It reduces the inflow of free water. Water emulsified by ethanol cannot be 100% removed with any pond filter.

Does it slow down fuel loading?
No. It is designed for standard dispensers; simply choose the compatible model to maintain normal flow.
