Base-plate: 8 hole openings. Thickness of the plate approx. 0.10". The gasket on the base-plate is squared and is a red gasket material with a slick Teflon-treated surface to ease the removal of the filter from the engine block after use. Gasket is held in by 6 pressed lips. Stamped: “X" and “3/4-16-S".
Case: Thickness approx. 0.018". There is a stamped spring in the bottom of the case, it is stamped “1".
Anti-drainback valve: Silicone. Its supposed to remain more pliable and seal better at higher and colder temperatures. Thickness of 0.041" with the outer lip having a ridge that is 0.063" thick. Total width of 2.05". Hole in center of 0.9". Stamped: “1".
By-pass valve is the typical design made by Purolator and also used in the PremiumPlus and the Toyota filter, it is a stamped spring mounted into the metal end-cap that holds the paper filter element. The spring hold a metal plate which seals the opening.
Filter element: Paper with a thickness of 0.031". 48 pleats of width 0.39". Filter element height of approx. 2.0". 74.88 sq. in. of filtering surface area. There was the funny string tied around the filter element, and tied in a knot. The seam for this filtering element was very nicely put together with a metal clasp. Metal end caps glued to each end of filter element. Metal support structure inside element to prevent collapse.
General observations: Another nice quality filter. The Purolator by-pass valve seems very hard to open, I don't know that there is anything wrong with this, I just note it, it's the design as used on the PremiumPlus and Toyota filters. The pleats in the filter were nicely spaced and the glue job holding the filter element to the end caps was OK, but a little sloppy in a couple of places. The anti-drainback valve in this filter is probably the best of the filters tested I would guess in that its silicone. The lubricated gasket which contacts the engine block is a nice feature, removal should be easy (but I don't find the other hard to remove). This filter is made in the USA. It wasn't noted on the filter what standard it met (J806 or J1858).
