Every part, line of code or supercharger system that leaves with the VF label stands for the paragon in design, engineering and performance. It means your car is running the best there is. After years of spirited use, more than 93 percent of VF Supercharging Systems are still running strong, many on their second and third owners.That’s a great testament to solid design and robust fabrication. That’s what we want VFE to mean.
