I am not sure this gizmo will give you 35HP but I can promess you'll be had for $69.95 if you buy one. Their add is very conservative. it will save so much fuel your tank will overflow. Exxon will be put out of business and OPEC will start playing cards.
It also comes with mustard and onion (optional).
You can also install one of those gizmo backward in your exhaust system. It is said to cure hemorrhoids.
Save your hard earned cash and don't get cought by those idiots.
