Review on 57S 4900 Performance Intake Kit by Chad Blanchet

I used it on a 2008 Saturn Astra XR. It replaces the restrictive factory airbox and is easy enough to install. I connected this to a VXR pipe for maximum airflow. Throttle response improved a bit, but didn't feel much better on the dyno. The intake noise has gotten louder, but in a good way. The only downside is the oil. It's simple, but you need to make sure your mass air flow sensor doesn't get coated.
