That is a Popular Mechanics artical that tested "fuel savers." One of the ones they tested was the Tornado Fuel Saver. It decreased the horsepower by over 10% and had no significant change in fuel consumption. Also, because you place it after your mass airflow sensor, if any part of it breaks off, it could really damage your engine.

if these things worked, the car companies would put them in.It would allow them to sell more gas-guzzlers.

good idea, poor design. it is placed to far up the airstream to make a difference, after all the twist and turns in the intake manifold any turbuince created is gone. besides most MAFs i know of are designed the striaghten the airflow for a acurate reading.

in fact they do, but they are designed into the combustion chamber or right at the intake port. IE - chevy vortec heads

why dont they put on free flowing exhausts and intakes for better gas mileage? its all about saving money, building it quick, but making the car good enough for driving. now you cant say because its not emissions legal because almost all companies have emissions legal exhausts.

now for this fuel saver, save the $70 or whatever and invest in an exhaust and intake. you will see better gas mileage with those. that thing is a pile of crap.

there are several reasons.
1. above all else, a car is designed to be a fine balance of everything. looks good and works good. comfortible and visually appealing. cheap but a good value. making it a race car and a groucry getter. powerful and quiet. free flowing = noise. and i don't think grandma wants to entire nieghborhood to know she is headed to church.
2. cost - its cheaper and easier to make a cast manifold instead of bended and welded header.
3. emissions, yes i said it. aftermarket products go thru different testing then OEM parts. and federial and CARB emissions are two different things, not all aftermarket product meet both. then there is the whole thing about heat transfer with headers and catiylic convertior warmup.
4. cafe requirements - if i'm not mistaken, if a compuny makes a large amount of extra clean vehicles then they have a little more room to play with on other vehicles(SUVs and sport cars)


also what aftermarket parts can offer 8Y/80kmile emission/10Y/100kmile parts warrenty?
