Otzal-Internal Plenam

200-600 tunable HP. This system was developed for the advanced nitrous racer and tuner.  It is capable of flowing 1500 pounds per hour.  The dual solenoid feeds from both front and rear allow for even distribution.  Easy assembly for on sight race track tuning.  Disassembles as one piece through the front of the plenum (great for tight firewall tolerances).  Take a good look at the thumbnails below.  Prices start at $2000.
