The airbox in the 23 has a little relief valve that can steal hot air from the engine compartment if the screens come clogged with snow. I rode my 22 in 3' of fresh today and the exhaust bog was pretty bad anytime I went to U turn around to the right back up the hill. Almost got me stuck a couple times. Today was the first time I ever had a problem but it was silly deep. The bog caused from the screen being covered is a workable bog. It's just like really bad lag. Riding with Doos today it really made the crappy bottom end of the Polaris Boost stick out. I wish Polaris could somehow clean up the bottom end. You guys who don't think there is a problem are kidding yourselves. And for guys like Rusty who think you can "clutch" around it, it just kills the top end. I wish I was a crappy rider like you guys so I could live in your dream world of the Boost being such a magnificent sled.
