What drivers are saying

From the testimonials on our site.

My turbo kicks in faster and I don't need to floor it to get the speed. The car is smoother and the jerky feeling when the turbo peaks is not there anymore. It seems like I have a smooth flow of power to redline.
Tony (2018 Lexus IS300)
Quantum Solenoid was quick and simple to install replacing my old one. This upgrade was worth it in 2 ways: it improved midrange power and gave more consistent hp figures.
Mykyta (Prius Gen 2)
Yoooo! I love this solenoid! Took the car to work and my route usually has no traffic so from the on ramp of the freeway I gunned it and I was not disappointed at all 🤘🏻🤘🏻
kuyaseb (Toyota C-HR)
I do feel the difference. Smoother transition, no spaceship feel. Speed wise, on frwy, feels like I'm in power mode without the setting.
priusmods_la (Gen4 Prius)
Hate to say it, but this thing is for real. Unbelievable! Don't take my word for it, just drive one with a Quantum Solenoid installed and you will know what I mean.
Rog (Prius V)
Getting to drive the demo car before and after the Quantum Solenoid install, all I have to say is, WTF! I hate to say it, but I was wrong ...
Pacifist (Prius Prime)
