My friend snorkels all his SXSs {last count 19} as soon as he gets one . His first Pioneer 1000 that he sold a few years ago just turned 40,000 miles and it's only problem so far has been wearing out tires . Dirty air is probably the cause of WAY more engine failures than not changing oil . Snorkel or at least put a pre filter of some sort on if you ride in dusty areas predominately . my 2 cents worth
