Review on 🚗 2.5-inch F1-Z Car Air Intake Turbonator with Dual Fan Turbine - Super Gas Fuel Saver Turbo (Black) by Clint Miller

I bought a pair of blue ones and left a raving review. I ordered them as a backup set. I can't give them the same positive feedback. The first ones I bought had an aluminum turbine fan and worked fine. The blades on them are plastic, and the power of the force generated is less. There seemed to be a noticeable difference. The blue aluminum ones also seemed to be of better quality in my hand. Not a waste of money but make sure you get aluminum blades when you order them. They must have a cold air intake system for them to work, or a similar setup where the air cleaner is in front of the turbos, but I can't think of any other way that would work the same way. If you have paper air filters, this will not work.
