Features

  • Sitting on top of your performance air filter, the Hydro Shield blocks water and microscopic particles from getting into your engine
  • Drive confidently through light showers, deluges or even sand storms
  • While repelling water, the Hydro Shield still allows wide-open airflow, letting your performance air filter deliver huge horsepower and torque gains
  • The Hydro Shield's embedded hydrophobic treatment creates uniform micron-sized pores that filter out water and debris as small as .005"
  • Expertly crafted from highly durable, racetrack proven polyester
  • Your Hydro Shield was engineered to work best with cold air intakes that position the air filter outside of the engine compartment
  • Available in three hotrod colors: Red, Blue and Black
  • Injen covers your Hydro Shield with a Lifetime Warranty

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.

Notes

  • For a proper fit onto non-Injen Air Filters, check the following measurements of your current filter:

    Base: The circumference at the bottom.

    Top: The circumference at the top.

    Tall: The height from base to top.

"I got a hydro shield for my AEM V2 Cold-Air Intake and it works great!! Ran it under the water when I first received it and the water just beaded up and rolled off. Doesn't interfere with air-flow at all and still lets the intake sound great! Overall an awesome purchase for the money as it keeps my filter nice and dry and protects it from debris as well. (If don't know the size to get, Medium fits AEM cone air filters)"

"This thing is a must, really! It is worth the price ,and health of your car. Ive gone through some major puddles in the past couple days ,and noticed that it deflects water off the filter. It is also a washable and dosn't interfear with your horspower gains. Thanks again Ingen"

"A neccessity if you own an Injen Cold Air Intake and don't plan on taking your bumper off every time you think it will rain severely! Little more than a fitted durable plastic bag, the Hydro Shield may or may not actually save your vehicle's engine from water intake during adverse weather conditions. For a little more peace of mind, however, $25 is definately a good deal. Injen needs a water bypass valve like AEM!"

"I had consistent problems with my engine cutting out when watter drops would hit my MAF sensor. Lots of rain and car washing since I installed the Injen Hydro Shield, and ZERO problems with water getting to the MAF sensor! P.S. I have a 2008 MazdaSpeed3 GT, with the Injen CAI."

"After reading other reviews, I did the sink test, and a very small amount of water seeped through the seams, but that is to be expected, if you are running a setup with a CAI, then you should know better than to park in a puddle and try to start it in a puddle as well - not only does it keep at least 99% of water away and let in air, it keeps dust and debris off as well to make the filter stay fresh longer."
