Good OEM replacement, but check the contents
Size: (Pack of 1)
This filter was perfect for my 2020 ram 1500, however I had to get a replacement because the gasket was not included in the box as delivered. I contacted the seller and they replaced it within two days. The replacement unit had both the filter, and the gasket in the box it should've been.

democracy in action or am I allowed to vote
Format: Paperback
This is a superb document on the history of voting rights in America from its founding to 2000. Well worth reading about the struggles of Americans to get the vote. The discussion of suffrage for all Americans. How those that had the vote trying to prevent other people from getting the vote. We struggle with this today, given that President Drumpf is more than willing to disregard the majority of American voters. Our democracy beware and here is the history.

Incredibly well researched
Format: Paperback
Purchased in light of the current election fraud/security debates. I learned nothing so far is new. Data intensive. Can be dry at times, though many of the quotes from historical figures are revealing as to prevailing attitudes.
