GreatRX350

Hi, i'm considering getting this on my RX350 2011. Just wondering if this item is worth it or am i going to end up with problems with sensors.

some people are saying that they do work but too worried about particles getting through their engine.

Has anyone installed this system? if so can you give me some feedback on it and also was it a difficult install that i have to get my dealership involved. thank you for any feedback.
