Should not be advertised as a cold air intake!
The outer end of the air box does not seal to the factory fender hole allowing hot air to get around it. Also, there are air intake holes on the top and front of the box that allow hot/warm air from engine heat to get in from under the hood. The fit was very hard on my Silverado. All the pieces were so tight that I had to force the pipe over very hard to get it to fit on the intake manifold. Very little space for engine tork/ rock. I have been talking to Injen with no resolution as of yet.
