I have been using only the Pure Power Filters now for almost two years. I have bought so many I am now a Pure Power Dealer. lol.

I am totally sold on it, but it is costly and will give sticker shock as compared to Fram, Wix, Ac etc. Not the same at all.
It is API Certified to filter down to 22 micron nominal. The really trick high tech machined bypass uses a check ball with spring and will not open unless the filter element is full of trash. It will not open when the oil is cold and at high pressure.

I just recently had a customer begrudgingly let me buy one for his engine, but when it was on the dyno and he saw in person how quick and how easy it is to check his engine with it, how quick and easy it is to clean and most of all how well it filtered he became sold like me. Then he decided to buy them for all his fleet trucks. lol.
The only similarity with this and the System 1 is that it is removable and cleanable. It filters better, flows more than anything available, and is fully 100 % high quality machined from aluminum billets. I guess I need to also post a pic of what the bypass looks like. IT is a high quality machined piece from aluminum billet that looks a little like a satellite from NASA in my opinion. It uses a steel ball with a long spring as a check valve and absolutely will not open when engine oil is cold. It will only open if filter element is fully clogged with trash.
Need any more info let me know.
