The Injen Hydro Shield is great for wet climates or places where water could get into the engine. It repels water perfectly however this does come at a cost. With the Hydro Shield on the intake it does decrease some of the top end power. It isn't enough to make a big difference but there is a difference. Just weigh the options though. Lose a little power and have a dry engine or have a little more power and risk engine damage.
