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.

Nitrous Master Jets are very accurately sized jet to jet and have very, very close flow characteristics "off the shelf".

For the discerning crew chief who wants absolute matched jet sets we offer:

Flow Matched set of 4: $60.00

Flow Matched set of 8: $100.00
