This advertisement is on millions of WebPages that use the google ads.. the specific ad will always match the make or model of car you are looking for info on.. so you may see "Supercharge your BMW for $XX.XX" someone else will see "Supercharge your Jeep" etc..
But reality is some these are either electric fans .. but mostly are Surbo, Cyclone thingies.. they have product names like SpiralMax, TurboMax, AirTwister, Turbonator ect..
They do not work.. a small electric fan does not have the pushing power to force air into the combustion chamber.. and at higher RPM's will cause an impedance to airflow just find any small fan and block it with your hand.. it will simply shear the air and is no challenge to you to block it.. perhaps a 24" industrial exhaust fan has some power.. running 240v or more ..but a 2" 12V electric motor..
Cyclones, Subo's.. right up there with fuel line magnets.. waste of money... a) they block airflow B) they make air flow turbulent.. c) anything short of forced induction or impeding air flow you try in the intake tube will be ultimately undone by the design of the intake manifold. Turbulent air is less dense than straight flowing air therefore provides less potential energy for combustion compared to a properly engineered intake design.. the designs of cars intake systems are pretty complex.. to think you can just arbitrarily stick something into the intake tube and improve the design is simple wishful thinking.
I have even found these things laying sideways in people air intakes, if you want one to test drop by and I'll give you one of the ones we have removed from peoples cars (with the owners consent) .. they'll end up in the garbage where they belong soon anyway...
