Any thoughts on which would perform better? The MTNTK Blowhole vs. 9 peice vent kit.

if I were to choose one over the other it would be the blow hole.

I have the blowhole on my T1100 and it works really well and in deep snow when the vents are covered, the Blowhole keeps removing hot air! Its amazing how much heat it takes out. No way a passive vent can compete. Take your time on the install. Easy to do project.
