As a red blooded american I love supporting small businesses and MDDP has been great. Will be buying constantly from this company.

This is a great product. It is super easy to install and fits perfectly. I added an extra quart in oil capacity and will keep my oil a little cooler. MDDP shipped it out immediately, and I got it quickly, too. Great Work!

The kit is perfect. Nice that it comes with the tool to remove the old nipple. I believe it will be a very worthwhile investment.

Aside from this being a great upgrade to make. MDDP was great to work with they’ll be getting my business and my buddies business from here on out.

When I received my oil filter + adapter for my LBZ Duramax I was so happy to find that my package came in early and I found a hand written note from Joanne thanking me for Choosing MDDP for my Duramax. I mean holy cow you don’t see that with companies. I will keep spending my money here and i suggest you do to. Thank you very much Joanne!!!

Super easy to install the adapter piece. Took longer to get the old filter off than to install the adapter and new filter. Super simple, easy to follow instructions.
No leaks or problems

For the price of any diesel oil filters especially a name brand went on smooth and just know it's cleaner
