Bests & Worsts Reviews from Amazon

The BOSCH filter is a mid to high level filter.. It has M20x1.5 top with a nitrile gasket. 20 micron filter media with 14-18 psi bypass made by a stamped steel spring on the bottom of the filter element.. the element can hold up to 14 grams of dirt/shavings/etc. In other reviews I noticed a trend of saying "this filter is heavier than other filters and must be better" yes, it's a heavy filter.. but, the extra weight is because the top part with the threading and oil ports is about twice as thick as the compared napa gold.. this will not have any effect unless your oil pressure is 100 psi(typical is 40) and you are worried about your filter blowing off.. the extra thick head may be to make it feel better than other filters.. Just my thought ;-) Pros: large filter inside canister Silicone anti drain back check valve Metal lined and metal capped filter element Cons: Cellulose paper on filter element (better to have synthetic) Stamped steel bypass (better to have actual spring like the napa gold in the picture) 20 micron filter paper (better to have 15 micron) My take: a good filter. I like the large size of the element. In comparing to the napa gold in the picture, I will take the larger filter element over the better built and smaller element of the napa gold *note: the napa gold was used for purposes of a engine flush and the BOSCH was used on a 5,000 mile mobile 1 oil change. This is why the napa filter looks cleaner And the Cat😞... I was going to retake the picture after she wandered off, but I forgot
