I have the Injen CAI and are debating on keeping the Hydro Shield installed year round on street and on the track. Does anyone have first hand experience if having the Hydro Shield will reduce performance?

Having the Hydro Shield on the filter does have it's advantages by keeping the filter clean.

 

I have an injen intake,havent installed, i live in pensacola fl, and it crazy at times with rain, i would like to know if it works good and does it hurt performance.
