I have been waiting a very long time for an item like this adaptor. I had given up looking for a long while. As soon a I got it I took all the Mickey Mouse crap off. Screwed it in place, put a filter on it and peace of mind. The shops DO NOT always change for filters. I have marked mine to check. You will not hurt your engine warranty, you will not have low pressure, you will not destroy the environment any more or less.
By the way I run a Shrockworks pan all underneath my 2010 4Runner.
