Nothing cools an engine's jets like water from your air intake. Whether you're driving through a slight drizzle or a typhoon, your motor is in real danger of drowning. Injen's Hydro Shield, however, stops water from sinking your vehicle. Riding right on top of your performance air filter, this durable polyester cover repels water while still allowing a free-flow of oxygen.
The secret behind the Hydro Shield's amazing success stems from its water repellent outer coating. It's crafted using a sophisticated embedded hydrophobic process, which creates uniform rows of micron-sized pores. These openings filter out water and debris .005" or larger!
You don't have to worry about choking your engine, though. The Hydro Shield purifies the oxygen while still allowing steady airflow-and consistent airflow means rip-roaring horsepower and massive torque. Plus, the Hydro Shield comes in three stylish colors: Red, Blue and Black.
- For a proper fit onto non-Injen Air Filters, check the following measurements of your current filter:
Base: The diameter at the bottom.
Top: The diameter at the top.
Tall: The height from base to top.

Great price and value, prevents my engine from getting water in it. Good look and tight fit. Easy install as well.

Installed this on my injen cold air intake for my civic. My car is lowered and does not have the protective splash guards anymore due to it coming off. This saved my car from sucking in water through the intake during the short rainy season of California. Definitely worth the buy.

i thought it would keep more water out rather then let it in and hold the water in
