Helps your engine breathe better.


Tornado improves air flow into your engine through a natural wind vortex. Tornado increases your vehicle's mileage by 1-2 MPG points*, so you can drive an additional 30-50 miles each and every time you fill up.


* Your mileage results will vary

The Tornado, it was the clear winner in our test. Normally the Chevy Van gets eleven miles per gallon, now it gets 12.2 MPG. A savings of about 11%. Based on this—I’d recommend the Tornado.

More Smiles Per Gallon

* Pro Tip:  After install, reset your vehicle's trip computer (Average MPG) so your car can figure out how much gas is being saved. Logging your mileage at the gas station is also a great idea, too. Total Miles Driven divided by Total Gallons Filled, equals your Miles Per Gallon. i.e. (640) Miles Driven divided by (16) Gallons Filled, equals (40) Miles Per Gallon.

—Bobby Likis, The CarClinic Network®


"Tornado installs easily and immediately improves drivability and fuel mileage."

—Sam Memmolo, National Auto Expert & Master Mechanic


Pays for itself

Improved airflow into your engine's combustion chamber creates a better mixture between oxygen and air-fuel particles, creating a fractional increase in power and mileage. Over time, the fractional increase in power and mileage results in savings.
