Like I said, the bottom of the filter should be even with the air dam. The filter should be up tight against the 90 degree rubber elbow. You shouldn't be able to see any of the sleeve the filter connects to.
i have one on my car, i didnt buy it with the larger k&n filter instead i used a shorter one from spectr u can see in the attached pictured it doesnt even come close to hanging past the front spoiler
