So far the Injen cold air system shows improvement in power & gas mileage. Only had it @ 5 days; verdict still ongoing.

I have not the opportunity to know how well the Injen intake performed without the hydroshield, but I feel after installing both products, is that it is doing its job. I've heard good things from other people who have bought it, and I can say I happily enjoy it as much as they do. It fit like a glove and looks heavy duty. I would greatly recommend this product to anybody who is looking for the extra protection this product can have to protect your engine and particles from damaging your engine.
