Query: No data to support the following but...

From what I can tell, my car (Toyota V-6) runs "better." Because I have no data to support the claim, I cannot assure others that the filter makes a measurable difference, but the car does seem to run better - no hesitation when I press the throttle as it did before I installed the filter. Have to think that breathing better, it runs better. As for the value - 50K before cleaning saves a big chunk of change. So all in:1) installed easily2) seemingly better performance3) saves money
