well....errr.....This might have been the case back in the days of carburetors. Swirling would help atomize the fuel. Hardly the case with fuel injection though where a highly atomized mix is injected just upstream of the valves. Also, a modern MAF controlled Fuel system needs a clean flow of air over the MAF to accurately calculate injector duration...
There is no point at all to these on a modern car..
