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. Covered by a Lifetime Warranty.
- 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.

it will help repel little amounts of water but won't be much use if it's pouring

Seems to work well. Imagine a sock covering your intake and repelling drops of water. Do not submerge your intake filter in water.
