Product Description

The AEM 30-3003 Water/Methanol Injection Inline Filter is designed to protect your WMI system and engine from harmful particulates in the fluid supply. Its stainless steel micronic mesh screen captures contaminants as small as 40 microns - far finer than most competing inline filters - ensuring a clean, consistent flow of water/methanol to your pump, nozzles, and engine.

Built from chemically resistant polypropylene, the filter housing is rated for use with methanol concentrations and is fully serviceable for long-term use. It installs quickly in-line before your water/methanol pump and is compatible with virtually any WMI system on the market that uses standard 1/4" OD nylon tubing. AEM recommends running this filter on all WMI setups - including their own 30-3300 and 30-3350 kit series - to maximize pump life and system reliability.
