I'm in the market for a Injen CAI and have some concerns. First off I noticed the CAI system for the Mazda3 has the filter head positioned near the bottom of the car, that's my main concern because I live in Florida and we get a few rainy days here not to metion the roads somethimes don't drain very well. I have a fear of hydro locking my motor because there is no splash guard to block water being sucked into the engine, I've seen some cars with the guard but I know it doesn't come in the kit. Where do you get the splash guards?
