Its a great filter, but, you need to be aware of a few things. First, it requires the use of a 16mm wrench. If you use an SAE wrench youll mess up the hex fittings. Second, replacement o-rings are not, at the time of this writing, available from Aircraft Spruce. They really should sell these, as disassembly for inspection could damage the existing o-ring and you definitely want spares if youre going to open and inspect the filter as recommended. So if you use this filter, order spare o-rings from Andair or elsewhere to ensure you have them. The product itself is great, but you need to prepare yourself if you use it.
