The import automotive market has grown rapidly over the last decade and what can be better than to have Acura's and Honda's still pulling strong with many of today's enthusiasts. Not to mention the fact that vast numbers of manufacturers are developing new product lines for imports. With that in mind, how can you be sure that the product you are getting is one of quality and right for your application? We have been researching Acura and Honda performance upgrades for the past ten years and have learned through experience what works and what doesn’t. 

All of the products we offer here are high quality products that you can count on to do the job. We select our products carefully, testing them to make sure that they perform as expected. As dedicated enthusiasts like you, we strive to push the limits of technology only to achieve the highest results possible. Our dedication to the motorsport is immeasurable and that's what drives us to bring you, our customers, only the best in quality and performance for your Acura/Honda.
