ZEX Nitrous System - 2005 Mustang GT

The COMP Cams ZEX Nitrous Oxide System for the 2005–2010 Mustang GT is a wet-bottle nitrous kit engineered to deliver progressive power gains from 75 to 175 horsepower. Built around a 10-pound bottle capacity and optimized for the modular 4.6L engine platform, this system combines reliable metering with proven Comp Cams engineering to add straightforward, controllable power without requiring major fuel system upgrades on stock or mildly modified platforms.

Wet-bottle systems inject nitrous oxide directly into the intake charge alongside fuel, eliminating the need for auxiliary fuel solenoids and complex fuel-pressure management on naturally aspirated engines. The progressive 75–175 hp range allows staged activation: operators can run conservative nitrous boost for street driving and cruise scenarios, then engage full power at the track or during spirited acceleration where engine load and fuel mixture are optimized. The 10-pound bottle provides sufficient shot capacity for repeated runs without frequent refills, making it practical for weekend track use and spirited street applications. Purple anodizing on the bottle assembly provides visual identification and corrosion protection under hood conditions.

Mustang GT owners seeking immediate, bolt-on horsepower without turbocharger or supercharger complexity will find this system addresses the fundamental power-delivery limitation of naturally aspirated 4.6L displacement. Proper tuning and jetting to fuel ratios remain critical—this is not a "install and ignore" modification. Buyers should verify that their fuel pump, injectors, and ignition timing can handle peak load at full boost levels, and that local emissions regulations permit nitrous installation and use.
