Obtained this air filter to enhance the performance/fuel economy for my 2011 RAV4.  I do most of my driving under 50 mph, which was using gas pretty fast.  Installation was a little bit tricky-you have to carefully place it in without tearing out wires.  After a week of disappointment, I remembered to reboot the cars computer it was stuck showing 21.1 mpg.  With my current tank of gas I am showing more than a 2.5 mpg improvement so far-pretty good considering its the V6 AWD model. And, the filter is guaranteed for beyond the life of this car, so I am definitely satisfied.

Power transfer is quicker & tighter, less hesitation on gear shifts, engine is running at a cooler operating temp and gas mileage is consistently running at its advertised maximum. Have had the filter in for about 6,500 miles now and of course have noticed no indication of dirty air filter performance loss where a normal air filter at this point would have. I may have noticed some minor hesitations, especially living in high altitude Colorado mountains where dust & dry air chew through filters! When I do get to clean the filter for the first time I am excited to see its lifetime qualities put into action!
