About Us

At INTENSE we design, build, install, test, tune and race what we sell. We spend the time and money necessary to make our cars the absolute fastest in North America in their respective classes. Then we offer you the most powerful parts along with custom dyno tuning, and back them up with the best possible customer service - both before and after the sale.

Our roots stem from racing late model GM vehicles and we have set dozens of records on the dyno and at the drag strip. Here are just a few of our more signifcant accomplishments.
