Key Features & Functions
Inline Filtration Protection
Installs directly in your system:
- Filters debris before it reaches injection nozzles
- Prevents clogging and restriction
- Protects pumps and solenoids
Because one clogged nozzle can ruin your tune.
The AEM Water/Methanol Injection Filter is an in-line filter that uses a micronic mesh screen to filter particulates as small as 40 microns.
Maintains Proper Atomization
Clean fluid delivery ensures:
- Consistent spray pattern
- Proper misting for cooling
- Effective knock suppression
Because water/meth needs to atomize—not dribble.
This allows a cleaner glide of water/methanol to be passed into the engine, not only protecting the internals of the engine itself, but also the working parts of the water/methanol pump too.
High-Flow Design
Built for performance:
- Maintains proper fluid flow
- Prevents pressure drop
- Supports high-output systems
Because restriction defeats the purpose of the system.
Run the AEM Water/Methanol Injection Filter in-line before the pump to give protection to both pump and engine. If you’re the use of a Water/Methanol Injection System it should greatly increase pump life to use a water/methanol filter.
Protects Critical System Components
Improves longevity:
- Reduces wear on pumps
- Prevents contamination damage
- Extends system lifespan
Cheaper than replacing your entire setup.
The AEM Water/Methanol Injection Filter prevents foreign particles as small as 40 microns from clogging or damaging pumps, injection nozzles check valves or glide sensors.
Durable Construction
Designed for harsh environments:
- Chemical-resistant materials
- Handles water/meth mixtures
- Built for long-term use
Because it’s constantly exposed to fluid and pressure.
The AEM Water/Methanol Injection Filter uses fittings to be used with 1/4inches OD nylon tubing, so it fits most Water/Methanol injection kits in the marketplace today.
Simple to install, takes not up to a minute
Polypropylene housing-rugged material that may be compatible with high concentrations of methanol
Large Filtering Area assure long service life and does not significantly reduce glide
Completely serviceable assembly, may also be disassembled, cleaned and reused for a long service life
Why You Need This on Your Project Car
If you’re running water/meth injection and don’t have proper filtration, you’re asking for problems.
The AEM 30-3003 Filter gives you:
- Clean, consistent fluid delivery
- Protection for nozzles and pumps
- Reliable injection performance under boost
- Improved system efficiency and lifespan
Because inconsistent injection defeats the entire system.
Ideal Applications
- Turbocharged builds
- Supercharged setups
- High-boost performance cars
- Track and race vehicles
- AEM water/meth injection systems
Final Verdict
The AEM 30-3003 Water/Methanol Injection Filter is a small but essential upgrade for maintaining system performance and reliability.
It keeps your injection system clean, efficient, and functioning exactly how it should.
Because protecting your setup is always cheaper than fixing it.
