Couple options. By an OuterWear prefilter at cfm.com. I disconnected the lower part of my cai were it bolts to the radiator frame and positioned the filter a few inches higher. I used zip ties to hold it up. You can also by a piece of plexi glass and and shape a shield. I did all the above cuz my filter was getting soaked.
I've heard some people using a 90 degree elbow from the old intake assembly to reposition the fliter upwards. If that makes any sense.
