- About Hydroshields
DC Sports Air Intake Systems improve the performance of your vehicle by reducing air restriction and improving air flow.
DC Sport Air Intakes provide the best of both worlds in heat protection and improved breathability. Every DC Sports Intake includes an air filter that requires no oil, therefore no chance in contaminating the mass air flow sensor, which can result in loss of power and higher fuel consumption. Also, your vehicle's mass air flow sensor will bolt right onto your new DC Sports Intake, meaning no check engine lights and better vehicle performance.
The Part number for this item is sri4301 and it fits 2002-2007 Subaru WRX / STI models. This item is 50 State Legal CARB Approved.
Introducing a colorful peace of mind.
Ever worry about water getting into your cold air intake system? For that added protection during those unsure moments, Injen Technology’s HYDRO-SHIELD PRE-FILTERS are race proven material manufactured from highly durable polyester. Uniform micron openings allow the filtering of debris .005” or larger. The HYDRO-SHIELD PRE-FILTERS are factory treated using an embedded hydrophobic process, which offers consistent airflow, water repellency and maintains horsepower gains. (Please note that this item is water repellent, not water proof).
Basically, the Injen hydroshield is a water shield and prefilter for your air intake system. It will allow air through and block water and large dirt particles, protecting your car and keeping your filter cleaner.
