I am thinking of installing a REAL louver beside my intake. I am thinking that my K&N will receive a stronger, cooler air flow. The louver will force more air as well, instead of it pulling air from behind the headlight. I am a little worried about moisture on rainy days and if it would improve the flow all that much.(cooler air) (more air) etc. I would love some feed back before I cut a hole in my truck:smoke2:
