Like the title says I am deciding which company to go with for a secondary intake kit for if my main one gets plugged off. Here is the SLP's one that mounts on the left top of the consol http://www.startingl...;productID=1139 and here is the other one that sucks from the top of the gauges and in from xtreme snowmobile air vents http://www.xtremeairvents.com/2.html . Any help would be greatly appreciated. Thanks guys Like the title says I am deciding which company to go with for a secondary intake kit for if my main one gets plugged off.

Any help would be greatly appreciated. Thanks guys There's been several threads on this subject already this season.  Some guys love the SLP and some hate it.  Seems it's design leads to quick plugging, but it can be wiped off pretty easily while riding, so who knows.  Haven't heard any actual feedback on the Xtreme, but I ordered one myself.  Haven't put it on yet.  May opt for the Doo version, as it has a connector between the vent and the airbox, which delivers cold air.  Bit concerned about the Xtreme version, because it will always deliver air from inside the hood.  Wondering if it will affect performance.  Then again, lots of guys running SLP flow-rites
