I'm not so sure about that one..... The only reason I say that is because stock O2 sensors are remarkably unsensitive... They basically operate in 3 reading zones...lean, stoich, and rich. They can't pick up minor changes, only major ones.Noltez said:Minor changes in airflow are picked up by the oxygen sensor & the fuel mixture is trimmed to compensate.
How does it make flow between the two more efficient when you just said that it restricts air flow ?HalfLiterBeater said:The gas mileage claim has its grounds though. If K&N can claim a mileage increase, through more efficient flow THROUGH the filter.... Then tornado can claim a mileage increase for creating more efficient flow between the filter and throttlebody. That much makes sense.
Because a vortex has been proven to promote more efficient flow. Now think about it. How is peak gas mileage achieved? By babying it and staying light throttle. At light throttle, the engine demands are such that the tornado COULD promote more efficient airflow because the air doesn't need to be moved in such large volumes as WOT demands....so the vortex effect will actually work and provide SMOOTHER and more consistent airflow.Kastivich said:How does it make flow between the two more efficient when you just said that it restricts air flow ?
