THE AEM WATER/METHANOL INJECTION SYSTEM ADVANTAGE
Water/methanol injection for forced induction (turbocharged or supercharged) gas-powered race engines is a proven means for effectively reducing engine inlet air temperatures and suppressing harmful detonation. This allows racers to reliably increase boost and advance ignition timing-without using high-octane racing fuel-for power gains of up to 20%. AEM's Water Injection Kits utilize robust hardware and deliver more advanced features than any other comparably priced water/methanol injection system.
Water/Methanol for All Boost Levels of Forced Induction Gas Race Engines
AEM offers two different water/methanol controller designs for gas vehicles:
One is boost dependent for forced induction vehicles up to 35 PSI of boost (kit PN 30-3300). The Boost Dependent controller has an on-board manifold absolute pressure (MAP) sensor with a molded-in nipple for a boost hose pickup.
The second controller (Kit PN 30-3350) features a multiple input design that enables users to install AEM's Water/Methanol Injection Kit on ultra-high boost vehicles (above 35 PSI) using a 0-5v voltage-based external MAP sensor.
Note: FOR OPTIMUM RESULTS, ALL WATER/METHANOL INJECTION SYSTEMS AND FLOW GAUGES SHOULD BE RUN WITH AN WMI INLINE FILTER (PN 30-3003). For additional insurance against unintended flow, particularly when the pump and tank must be installed higher than the injections nozzle, we recommend adding our optional High-Flow Low-Current WMI Solenoid (PN 30-3326).
Features
- Terminated harness features positive lock connector with integrated pump ground circuit and additional wire for optional on/off flow solenoid
- Includes "Boost Safe" readiness failsafe system
- One machined billet injector with integral check valve to prevent unintended flow
- Recirculation-style pump with integral fittings for quiet operation
- LED dash light for system status and low fluid warning
- 20 ft. of high-pressure Nylon injection tubing

Manufacturer's Warranty — AEM

Manufacturer's Warranty — AEM
AEM (Advanced Engine Management) warrants to the original consumer that its performance products will be free from defects in material and workmanship for twelve (12) months from the date of the original purchase. Coverage runs to the original purchaser only and is non-transferable, and implied warranties are limited to that same 12-month term. A product that fails within the period is repaired or replaced at AEM's option — that is the sole remedy, it cannot exceed the original purchase price, and AEM disclaims special, incidental and consequential damages. The Bosch LSU wideband UEGO oxygen sensor is a wear item with a limited life and is not covered; AEM lists replacement Bosch sensors under a separate 90-day term. Not covered: improper use or installation, accident, abuse, unauthorized repair or alteration; normal wear and required maintenance; improper handling, storage or lubrication; reversed polarity (+ and - wires crossed); acts of God; and cosmetic damage such as nicks and discoloration. A warranty return needs a valid Return Goods Authorization (RGA/RMA) number, prepaid transportation and a dated proof of purchase, and AEM must receive the product within 30 days of the RGA being issued. AEM requires the installer or end user to contact its tech line before an RGA is issued — do not return a product or request an RGA before that call, since most issues are resolved over the phone. Outside the warranty period, most AEM products other than discontinued items can be replaced at a discounted rate once the faulty unit is documented as field destroyed, again with an RGA issued first.
Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by AEM. Contact us if you need help with a warranty claim.
