I have googled and read on the forums but have not found quite what I am looking for. I am looking for an intake to replace the stock one on my 2012 rzr4 and the one's I am interested in are UTV Inc, UMP, and the D&L. I have not been able to find much comparison between the UTV and the UMP intakes. They look almost identical from what I can tell other than the cap. What are the main differences between the two and how are they holding up to abuse? Are any of you running the D&L and how does it compare to the others? I am primarily going to be riding in dusty conditions. Thanks in advance for any info!
