VRSF makes an identical unit, S&B filters and all, just their badge on it. With the running around, cutting, time spent doing all of this, I don't think you saved yourself much money
Good job on doing it yourself, but i'm just not a fan of those metal capped cheapo filters. Every time I see them on a car they're all rusted, etc.
