This is my second Volant intake, and I will keep buying them! There was a noticeable increase in intake noise from half to full throttle, which is normal and sounds great. The fit is a little tight. I actually had to rotate the filter bellow so that it would fit in the air box. Other than that, it fit great. I did add a tuner after the intake and it really woke up the engine.
The installation process would have been much easier, had all of the necessary parts been shipped. Having to purchase parts from a local hardware store that were missing from the package put a damper on the entire project. Having said that, I can definitely notice a difference in performance. Engine RPMs are lower, gas mileage has seemed to improve and the motor has a subtle, but notably deeper sound.

Overall Volant makes a great product. I've used their cold air intakes in my last three trucks. The only issue I had with this intake for the SS was there was no hole for the factory sensor. Leaving the sensor off causes the engine light to go on. I needed to drill a hole in the air box and modify it to fit to avoid this.
