STILLEN Infiniti Q50 Supercharger Now Available for Pre-Sale @ Whitehead Performance

STILLEN and Whitehead Performance are proud to announce that the Infiniti Q50 supercharger is now available for pre-sale here: Whitehead Performance STILLEN Q50 Supercharger.

Debuted at SEMA on the STILLEN Q50 build, the Infiniti Q50 supercharger has been eagerly awaited by many patient Q50 enthusiasts across the US and around the world and now the wait is over!


500 Horsepower Supercharger

Get ready to unleash the Q50’s true personality with this supercharger system! Around the office at STILLEN headquarters, the development of the Infiniti Q50 Supercharger became known as the SM500 project.

In addition to making exceptional power, this supercharger kit also includes the following features:

  • Air to water intercooler for more efficient and effective cooling
  • Increased runner length for increased torque
  • Completely sealed, self-lubricating supercharger system eliminates having to run additional oil lines
  • No hood replacement required
  • CARB approved and 50-state legal
  • Designed and manufactured in the USA
  • 3 year/36,000 mile warranty



Before donning the STILLEN logo, this supercharger was thoroughly tested to ensure maximum quality and performance by our in-house Research and Development team. However, to truly test this supercharger’s limits, it was put through its paces and driven from STILLEN headquarters in Costa Mesa, CA to the SEMA show in Las Vegas, Nevada and back by STILLEN Vice President of Business Development, Kyle Millen. After the drive, Millen had this to say, “The Q50 drove exceptionally well the whole way. There were a few stretches of road where I was able to open up the car and I was very happy with the power delivery as well as drivability.”

With results like this during testing, we have no question about this supercharger system’s quality and reliability. As such, we are offering a 3 year/36,000 mile manufacturer’s limited engine warranty on this kit.
