AEM Water / Methanol Inline Injection Filter

AEM Water / Methanol Inline Injection Filter | Clean Flow Protection

Protect your water/methanol injection system with the AEM Inline Filter. Prevents nozzle clogging & pump damage with a 40-micron mesh. 

Ensure maximum reliability and consistent spray performance from your water/methanol injection system with the AEM Water / Methanol Inline Injection Filter. Liquid water/methanol mixtures can easily carry debris, dust, or contaminants from filling bottles or reservoir tanks. Left unfiltered, these particles can clog fine-atomization nozzles or accelerate internal wear on high-pressure injection pumps.

Engineered with a high-flow 40-micron stainless steel mesh element, this inline filter captures fine debris before it ever reaches your pump or nozzles, without restricting liquid flow or dropping line pressure. Its durable, anodized aluminum housing is built to withstand harsh engine bay environments, high pressures, and corrosive chemical mixtures. Featuring leak-free fittings, the filter integrates seamlessly into standard 1/4" OD nylon injection tubing, making it an essential, easy-to-install safeguard for any street or performance water-methanol setup.

Best Uses

1. Custom Water/Methanol Injection Systems: Ideal for turbo, supercharged, and high-compression naturally aspirated performance builds.
2. Nozzle & Pump Protection: Protects sensitive magnetic solenoid valves, high-pressure pumps, and fine-atomizing spray nozzles from clogging or abrasive damage.
3. Preventative Maintenance: Excellent upgrade for daily drivers, track cars, or drag vehicles relying on meth injection for knock prevention and lower intake air temperatures (IATs).

Features

1. 40-Micron Stainless Steel Mesh Filter: Traps fine particulates and debris while maintaining full fluid flow and line pressure.
2. Corrosion-Resistant Anodized Housing: Built from high-strength billet aluminum to handle methanol exposure and harsh under-hood temperatures.
3. 1/4" Quick-Connect Fittings: Designed to plumb easily into standard 1/4" OD high-pressure water/meth nylon tubing.
4. Reusable & Washable Element: The internal mesh element can be easily removed, cleaned, and reinstalled for long-lasting performance.
5. Compact Inline Design: Fits neatly along fuel or injection lines in tight engine bays without requiring custom mounting brackets.

Benefits

1. Prevents Nozzle Clogging: Maintains consistent, fine mist atomization to ensure accurate air-fuel ratio and intake cooling.
2. Extends Pump & Component Life: Safeguards high-pressure water/meth pumps and solenoid valves from premature internal wear caused by abrasive debris.
3. Ensures System Reliability: Avoids lean conditions or boost-cut events triggered by interrupted methanol delivery under high load.
4. Low Maintenance Costs: Reusable filter design eliminates the need for frequent replacement parts—simply clean and reuse.
5. Quick & Simple Installation: Plumbs directly in-line between the reservoir and the pump/nozzle with standard push-to-connect fittings.
