When you restrict air flow the computer will adjust mixture, valve and spark timing and other factors, but only up to a point. Once you constrain the airflow sufficiently the ECU will start to bounce close to soft and hard limits, and will eventually throw a trouble code light Gene. |

Right. The reason all sorts of things get sold, accessories for cars, bikes, guns, sound systems, health and "wellness" items, etc. is that they create an expectation that they'll give a benefit, so the user perceives they've gained one and are happy with it.

I think they sell plenty of them, and customers simply change habits (aka: driver's mod) easily enough to see what they're expecting...lead foot, wow that feels better now. Slow it down some, yeah, it improved the mpg just like the box said it would.

For me unless your racing use oem toyota air filters mine was only $15.00 from my local dealer. At 18k miles and 1 year old my filter didnt look dirty, performance was fine but after putting new oem filter my fuel mileage went up slightly. I trust Toyota's research and will use only Genuine Toyota oil and filters. My overall avg FE is 43.4 mpg.My Daily avg the last few days is 52 mpg.
