APSG Oil Filter Funnel | Compatible with S

The two piece design of this funnel makes it messy and more trouble than it's worth. 1) The top funnel portion is threaded the same as the neck so if you try to unscrew the entire funnel, only the top portion will come off. You will then need to unscrew the neck from the valve cover filler leaving you with two sections that leak. You could try to unscrew it from the base but this can be awkward if you don't have the space to get a good grip on the slick neck. Too much trouble. 2) The two included rubber seals are flimsy, thin and do not stay in place. 3) The neck has a ring at the base of the funnel that retains fluid which makes even more of a mess that is difficult to clean. 4) Cheap materials and build quality. A traditional cone funnel is far better than this. Wasn't worth the time or effort to clean and return it for a refund.
