ZEX EFI Nitrous Systems

Product images may differ from actual product appearance.

Dry or wet, these systems have a patented feature called Active Fuel Control that checks nitrous bottle pressure and then adds or lessens enrichment fuel so engines never run too lean or too rich. Systems activate at wide-open throttle and use advanced electronics to monitor an engine's throttle position sensor, which makes using them easy and reliable. Major components are preassembled for plug and play installation (estimated 2 hours). Dry systems are ideal for stock or high-performance naturally-aspirated engines and many fuel injected applications. Wet systems work on stock, fuel injected, and highly-modified turbo or supercharged applications.
