After installation we noticed right away an improvement in the throttle response and pick up. It is a little noisy but that is to be expected. Our Kia Soul Exclaim is only a 2.0 liter, 4 cylinder engine with the EcoDynamic Feature. It seems quicker now and the mileage so far has been around 34.5 MPG! Much more than advertised. Every vehicle we own has a K&N Filter in some fashion and we Always see an improvement in performance.
Poor Quality Control
I must say after eager anticipation the packaging of this item reflected poor quality control and ultimately an unnecessary inconvenience. Too my dismay, after disassembling the factory system and removing it I found the package included the wrong size filter. This led to a wait of almost a week while I waited for the appropriate unit. It meant my vehicle was then out of service. AutoAnything relieved themselves of the matter by referring the issue to the original distributor.
