Me ha gustado el propio filtro y no me ha gustado que solo venga con los enganches de tuvo por presión y no traigan para tubería flexible roscada.

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.

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.
