## Overview

The AEM 30-3003 Water/Methanol Injection Filter is a high-performance inline filter designed to protect your engine and pump by filtering particles as small as 40 microns. Featuring a rugged polypropylene housing compatible with high methanol concentrations, it installs in under a minute and supports flow rates up to 43 GPM. Fully serviceable and reusable, this filter ensures long-term reliability and optimal water/methanol injection system performance.

## Description

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. This allows a cleaner flow 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. Run the AEM Water/Methanol Injection Filter in-line before the pump to protect both pump and engine. If you are using a Water/Methanol Injection System it may greatly increase pump life to use a water/methanol filter. The AEM Water/Methanol Injection Filter prevents foreign particles as small as 40 microns from clogging or damaging pumps, injection nozzles check valves or flow sensors. The AEM Water/Methanol Injection Filter uses fittings for use with 1/4inches OD nylon tubing, so it fits most Water/Methanol injection kits on the market today.

Review: Awesome filter, easily serviceable - Not sure what other reviewers were expecting, it's a great product! I don't have a filtered bulkhead, nor a filter anywhere in my methanol system. I run ~33 gpm of methanol as my extra fueling in a turbo application. I got a piece of debris stuck in my injector nozzle and it tried to take my motor out running it lean for a brief second. This is a coarse 40 micron filter that would have caught that debris, but it's not such a fine filter that it will impede flow for a high flow application. I've read it's good to flow up to 43 gpm of methanol. It fits snugly in the housing. My filter did not have the AEM logo anywhere on it, nor any logo. Just solid black, which is fine, nobody sponsored me, I don't care to sponsor anyone.
Review: Perfect For Water Methanol Injection - So glad I installed this just before my injectors! Before using this I had no idea so much sediment was traveling through the pump and into the engine. Everything about this is simple; installation, checking, and cleaning. The cap simply screws off so you can take it to a sink for rinsing. Most of the sediment gets captured in the part that stays inline but a squirt from a water hose, carb cleaner, WD-40, or even just running the water injection will quickly wash out the sediment. And it attaches with push-lock connectors so if you want to pull the entire assembly, it is quick and easy. This has been installed on a daily driver with a modified 12 valve Cummins for about a year through ambient temperatures ranging by about 100 degrees F. There have never been any leaks. For a while I noticed my water injection was still coming on under boost but hardly using any water. Sure enough, this filter was clogged with mud. After quickly cleaning the filter the water methanol was working again as it should. This is a must have. I ordered in 2018 and received this filter just as it is advertised.

A: You can install pre or post pump - just make sure fitting to tank has a built in strainer if placing post pump.

**Q: Looking to replace the screw-in push-to-connect fittings. are they 1/8 npt?**
A: I am pretty sure they are 1/4 NPT.

**Q: Boost juice for 1991 Nissan 300zx twin turbo Z32-D series 5 speed**
A: Yes it’ll work

**Q: My aem pump is rated at 300psi and this specifically states 150psi max. What’s the deal? Is there a 300psi compatible option?**
A: What's your pump part number? This is because the pumps by AEM are rated at 10Amps @200PSI.

### ⭐⭐⭐⭐⭐ Great methanol filter
*by R***F on February 8, 2024*

Installed on an existing system on a Diesel so fittings were worthless for me, a nice option would have been no fittings or different choices
