Frostbite- I have seen people comment on how they like their Timbersled intakes. I just think if you ride alot of deep powder where the pow just piles up on the hood, your under the hood temps increase dramaticly. And those are usualy the times when you want every last hp. But when those conditions are not present, I think the Timbersled preforms just fine w/ venting in the hood like "rigrat" states. I was suprised that I did'nt poke any holes threw the frogskinz vent when I mowed over some timber several times. I will probaly be adding some heavier vents down the road. Plus I noticed the engine noise is higher and the weight loss is awesome!
