At the 2017 SEMA Show in Las Vegas we received a lot of great feedback regarding TopDog-V and our new product Filteröl.  We took these comments to heart and have been retooling to make some minor changes.  We are almost ready to relaunch, hopefully in about three weeks.  We will keep the SEMA special pricing in place until at least April 7, 2018.  Please see this link for further information.

We will be exhibiting at the NAFA EXPO in Anaheim, CA  on April 25-26.  If you are engaged in fleet management or operations, please let us know and we may be able to arrange for a free exhibit hall pass for you.
