Just an update,
A few months ago I installed the first Advance Auto filter that I bought, well now I just changed oil and cut it up..
The purolator prem-plus equivalent that I used before had 66 pleats giving an area of 247 sq in., this AA filter had 53 pleats for an area of 199 sq in. That shows about a 20% reduction. The length and pleat depth dimensions were the same for both filters.
Both filters had a string around the cartridge, The purolator had metal endcaps that fully enclosed the ends of the pleats, the AA filter had flat endcaps that had thick glue that sealed the ends of the pleats but did not curve up around the ends like the purolator metal caps did. The AA filter endcaps were not metal, and were not the same fiber material as the new e-cores, and also were not the same cardboard as the Frams either. Best I could tell it was still a fibrous material but very stiff...all the pleats were secured well and no gaps/rips/defects, spacing was not perfect, but close.
My personal verdict- easily worth the price when they were half price. At full price though I would buy the regular purolator (I don't know, they may not be using metal caps anymore either- I'll see next time I get one I reckon.). These should be fine for 3k intervals, probably more But I've always done 3k OCIs anyway.
There ya go, they are obviously purolators, but NOT exactly the same as the Premium-plus..at least as far as number of pleats anyway...20% difference.
