Description

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.

The hydro sheild is mint! The thing looks great, comes in all the right sizes, and is rather easy to install, especially with a third hand nearby, to hold the filter. Looks even better than the pictures show, and WoW. It really keeps that filter dry! Ideal if you have a turbo, and want it to last.

I recently put this Hydro shield the c.a.i on my dodge ram hemi to keep road mist from entering the engine. The shield blocks 100% of water and slipped right on. I would recommend this product for anyone with a cold air intake.

I had trouble with my cold air intake absorbing water then I couldn't get up to boost. This solved my problem now my car is running a lot better. Highly recommend.
