I purchased the Hydro shield after putting on a cold air intake on my Ford Focus. Hydro-locking an engine using a CAI is a very debated subject and I wanted a little more piece of mind so I bought The Injen Hydro Shield. I won't be crossing any deep water but if I get caught in a heavy downpour I'll have more confidence with the Hydro shield installed.

Good buy for the price, as long as you know what size your intake is, its easy and fast!

Mildly throaty engine sound, a bit of extra pep, looks cool under the hood.
