Good to know

  • Note; it is important to follow the installation instructions and to insure the fuel system has the capacity to supply the total power of the engine plus the added power of the nitrous system.

Important: this product runs on nitrous oxide (N2 PI), a gas we do not supply and which is currently difficult to obtain. It is your responsibility to find a local supplier of gas for professionals. NOS bottles do not comply with CE standards (they do not carry the PI mark): only CE-approved bottles may be used. European manufacturers offer bottles approved to contain this gas; please check the applicable standards and verify the manufacturer's origin and compliance before purchasing. NOS fittings are not metric (AN / NPT threads depending on the part numbe PI): plan for the adapters needed for your installation. Please comply with the regulations in force in your country.
