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, 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 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.
