Take a flashlight and look into the intake, you will be able to see the impeller and the damage it may have taken. I got better results with the solas 12/17 than with the stock. Difference is minimal though, but i actually think the solas is a tiny bit cheaper than the stock. I haven't tried the skat, so i dont know about that one, but i would certainly recommend the solas
