They say that this little fan can give you 5-15 more horse power, and not just that it could save you money on gas to. The Dual Propeller of Turbo Fan Intake Fuel Saver spins with the engine speed while generating a maximum force that creates powerful airflow into the combustion chamber at high speed.
Once the engine is started, the propellers spin to create a maximum turbulence in the incoming airstream to allow enhanced fuel atomization in the combustion chamber, resulting in significant increase in horsepower and better fuel millage. Its a universal fit for all vehicles with intake hose. It works on gas or Diesel engine. It,s easy to install takes just 3-10 min to install.
I got one from ebay just to test it out. I'll see if what they say is true. I'm going to test it out in two different cars just to see if it works the way it is advertised. I'm testing it in a 2001 and a 1978 truck. I'll let every one know how the test goes.
I tested this F1-Z fan on more than 2 cars and the test was a fail. It makes the opposite of what the advertise say's. It's just a waste of money. Not just that it wasn't easy to install either. The funny thing is that it will pass a smog test but you do lose horse power. I recommend people not to buy this. It would make you waste more money.
