![Universal V3 Water/Methanol Injection Kit w/40 PSI Max HD Controller [No Reservoir, Race/Diesel]](https://www.jegs.com/images/mini_750/0/017/017-30-3303.jpg)
Vehicle Info NeededUniversal V3 Water/Methanol Injection Kit w/40 PSI Max HD Controller [No Reservoir, Race/Diesel]
Ships on 11/02/2026
Lowest Price GuaranteeWater/methanol injection cools the intake charge and helps suppress detonation, so a boosted gas engine can hold more boost and timing on the fuel it already runs. This V3 kit pairs the heavy duty controller, rated to 40 psi, with no reservoir, so race and turbo diesel builds can run their own tank.
AEM 30-3303 Compatibility Notes:
- HD controller is rated up to 40 psi and has a barb fitting to connect the boost line.
- No reservoir is included; a fitting is supplied for a third-party tank.
- Interchangeable nozzles let you match flow to your power level.
- An LED system status light is built in.
- Sold without a reservoir, so a suitable tank must be purchased separately.
