Review on Injen Technology SP1331BLK Cold Air Intake System by Ryan Carter

The OEM engine setup was definitely missing a click, so I feel like I noticed better throttle response with this system. Fearing water ingestion, which I think is a minimal risk as everything is surrounded, I bought a pre-filter to go through this filter to give a little more reassurance. I only had the car for one tank of gas before running so no real gas mileage data, but less restrictive airflow should result in slightly better fuel economy. It's definitely louder - more high-pitched tuner noise than stronger noise - but it's only a 4-cylinder engine, so I guess that's to be expected. Nothing is stopping me from buying again.
