I received the filter on time and I was able to install it with ease. On the 1st tank of gas I had 2MPG improvement. I continue to average 2 to 4 MPG better.

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.
