the stock air filters if you want to call them that, are very restrictive. any amount of snow on them and air flow suffers. we see this with RMK's bogging etc. is the result. we thought something else was going on. nope that was it. we removed the foam just leaving the fine screen and added flow rites. that made a big difference. no bogging after the mod. while maybe the stock set-up is fine. it's not when any snow gets on them. more air won't hurt. we don't like the SLP set-up for the pro-ride. the axys one is fine and we use them a lot. so yes we have used flow rites on the pro chassis a number of times.
and yes it's all the little things that add up to make more power. the air box mod. a lone makes 2-4 h.p. depending on the sled. 600/800
