03-04 Flux 4 Nozzle Set

200 HP gains.  The Flux 4 was the first to break through the 800 HP barrier respectively.   All Flux Hellfires use a custom nozzle like their little brothers above, but have a large flow rate and discharge coefficients higher than any part on the market.  The injection rate is lightining fast and cylinder pressures can exceed the limits of the stock head gaskets. Studs are a beneift, but failures of the stock gasket could still be experienced with a Flux 4.
