AEM V3 Water/Methanol Injection Kit - Tank-Less, Multi-Input

The AEM V3 multi-input water/methanol injection kit gives tuners who want an alternative to boost-dependent control a flexible triggering option. The multi-input controller triggers flow from a 0-5V external MAP sensor, frequency or 0-5V MAF, or injector duty cycle (IDC), so it works on high-compression naturally aspirated engines (via MAF/IDC) and ultra-high-boost setups above 40 PSI (via external MAP). This tank-less version ships without a reservoir so you can integrate a custom or third-party tank, and includes a single V3 nozzle for enhanced atomization of the water/methanol mixture. Optional wiring for a water/methanol solenoid is built into the harness.
