My 2001 SLE has improved in mileage and horsepower, My 1994 SE with 250,000 original kms came right back to life. No complaints from anyone so far.
The Fuel Genie is described as a fixed counter rotating screw (it does not move) and fits in the air intake hose 4 to 6 inches from the throttlebody. Hope some of this info helps more to follow.
Seriously though, how much total HP do you have now with the Fuel Genie? I've seen what other similar products have claimed.
So this "counter-rotating screw" does not move? Just a piece of plastic that sits still in the hose as air goes by it? I'm confused.
