Not sweating the detail.. IMO.. Please create a true cold air intake with a enclosed and insulated air filter can. And a insulated pipe. There is plenty of room to route inlet through the cold air opening into a box. Your system is not anything special over others at this point. And the real testing videos on this forum (and some in the past few days) show non increase of acceleration. Especially when heat soak in real world driving (not on a dyno with the hood open) is so easy with this type of unprotected design.
Many of us will pay more for a system that has measured results to keep no outside air temp increase.
So you want a filter inside your stock airbox? What type of insulation did you want to use? Also about dyno testing with a hood open is for saftey of the motor when your driving with the hood closed there is air being blown over the engine there is no air flow when your on a dyno. Lastly im no forcing anyone to buy the intake we made it as a option for some no one said you have to buy this.
Also like I said we only had a day to produce this intake if we had more time maybe I could have made a air shield for it as well. If you would like to bring your car to us to use for a few days and you want to help develop it you are more than welcome. We have had cars come from as far as maryland to help develop items.
