      If you really want to keep your engine running as perfectly as you can and want a better higher quality oil filter MDDP is definitely the place to get the only trusted adapter for the cat filter and filters so pick one up you won't regret it

      This is not the 1st time I've bought this product. The turn around time from payment to delivery is absolutely insane. Could I save a few bucks shopping around? Maybe...but I dont think I could get the quality, a rapid delivery of any products from MDDP will be a returning customer for the foreseeable future.

      Been buying products for my 2016 Duramax from MDDP since I bought it new. Mark always has great stuff for your diesel at a great price. He has answered my product questions and has given me tips for my Chevy over the years in a timely manner via email. Catch some of the DIY Videos...
