A quality Professional alternative to common "Kit" jets.

Are you hurting parts and it makes no sense? It's your jets that are the problem.

Nitrous Master Jets are CNC machined with the orifices final sized to a jet size tolerance of + .0002 / -.0000.

Quality control measurements are taken to 50 millionths (.00005) of an inch accuracy.

Tight tolerances allow for even cylinder pressures and exhaust temps resulting in more confident tuning.

Lazer etching the size eliminates the distortion and erratic flow caused by stamped numbered jets.

to the highest standards
