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. ## Features - Simple to install, takes less than a minute - Polypropylene housing-rugged material that is compatible with high concentrations of methanol - Large Filtering Area assure long service life and does not significantly reduce flow - Completely serviceable assembly, can be disassembled, cleaned and reused for a long service life ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0032W3KH8 | | Best Sellers Rank | #73,482 in Automotive ( See Top 100 in Automotive ) #87 in Car Fuel Filters | | Brand Name | AEM | | Compatible with Vehicle Type | Cars, motorbike | | Customer Reviews | 4.6 4.6 out of 5 stars (140) | | Global Trade Identification Number | 00840879020941 | | Included Components | Water Meth Components | | Item Type Name | Water Meth Components | | Item Weight | 0.09 Kilograms | | Manufacturer | AEM | | Manufacturer Part Number | 30-3003 | | Manufacturer Warranty Description | Manufacturer warranty | | Model Number | 30-3003 | | OEM Equivalent Part Number | 30-3003 | | Outer Material | Stainless Steel | | Product Grade | Replacement Part | | Style Name | In-Line | | UPC | 764885209254 840879020941 | | Unit Count | 1 Count | ## Product Details - **Brand:** AEM - **Item weight:** 0.09 Kilograms - **Outer material:** Stainless Steel - **Product grade:** Replacement Part - **Vehicle service type:** Cars, motorbike ## Images ![30-3003 Water/Methanol Injection Filter - Image 1](https://m.media-amazon.com/images/I/81QUEb3AckL.jpg) ## Questions & Answers **Q: Where to install.
