AEM’s Water/Methanol Injection Filter can filter particulates as small as 40 microns. It protects the working parts of the water/methanol system and the engine from particulates in the water/methanol mixture when installed in-line before the water/methanol pump, and can be used on virtually any water/methanol injection system using ¼†OD tubing.
