On a lot of the other forums the poor airbox design of the RZR is a hot topic but i don't see it getting talk about much here. are you guys not having problems with dirt getting past the filter and into the engine?

 

I have checked the air filter and I do not see anything that makes me worried on my Gen 3 RZR.

I only have 100+/- miles mix of fairly heavy sand and hardpack dirt/grass (there is "fine" sand and not so "fine" sand and Silver lake is not really fine...)
