ZEX Nitrous Systems for Nissan applications are the only direct fit nitrous system on the market today for the 350Z model. These kits include a custom designed billet fuel adapter that simply bolts on to the factory fuel rail, avoiding any cutting of the factory fuel lines. Because of the 350Z’s higher than usual base fuel pressure of 51 psi, also included is a custom set of tuning jets that not only maximize power but engine safety as well. ZEX patented Active Fuel Control reads the nitrous bottle pressure and adjusts the fuel enrichment accordingly. This unique feature ensures that you always have the optimum ratio of nitrous and fuel, never too rich, never too lean. TPS sensor activation enables the nitrous system to activate at wide-open throttle, precisely and reliably, every time.
