Exact fit

Same dimensions as OEM. Both the filter and gasket were an exact match. Would definitely buy again.

Returns were very simple

I had the wrong transmission filter and I’m not sure how you would ever change the CCV filter if you have the original one in your truck. The cartridge that is on the original truck cannot be opened to put the new filter in. It’s all one piece. To return and exchange it was extremely simple. 2018 6.7
