The Leading Source for VW Performance and OEM Parts

Volkswagen invested a great deal of engineering in the development of the water cooled motor, making it one of the finest small car engines available for high performance tuning. You may already know that an engine is a complicated system. We offer everything you need to make your powerplant perform. Because an engine is complicated, it takes more than just a bunch of parts to make it work right. Choosing what it takes to make it perform correctly is what SportTuning is all about. Through long experience and personal testing, we have worked at eliminating the frustrations of mediocre design and bad selection. The performance levels vary to match your demands, or as is often the case, your budget.
