It does as it is suppose to, install was rather straight forward although an install instructions would have been a bonus. Came with 2 hoses and a roll of rubber to seal the edges, only thing is I was unsure on how to proceed so I just did what I thought was best after watching a few videos online to see what everyone else did.
As seen in the picture I decided to line the edge of the top to help seal and keep vibrations to a minimum. I also line some of the lower section to help seal the hot air from getting into the box, but you are limited on the amount provided so plan it out before cutting it up.
Living in Arizona with the summer coming, I do hope this helps with keeping my intake temp lower...but we shall see.
Overall I am satisfied with this product and it definitely gives a cleaner look, just have to clean up my engine bay as it is duuuurty...lol
