The part that we received was extremely high quality and it definitely made a difference to the intake noise in the mid range when the engine is under load. one slight issue was that the foam was very thick and firm and made it a struggle to insert into the old filter box

Very high quality products along with great customer service. It would be nice if everything else under there was made this well. Installed just the plugs for now and even that made a difference in sound without those factory resonators in there any more. Freed up a lot of space too.

Love the enhanced sound and how it freed up space under my hood. Over-built. The way I like it. Shipped and delivered fast too!

Excellent product, would be nice if it has installation guide

One week in, I'm pleased with this mod. I'm not handy, but install was simple, despite there being no instructions. (I watched a video of a Perrin intake install to get the gist). Be patient and fully remove the rivets to take off the angular resonator; next time I remove the bumper, I'll put painters tape by the headlights for protection during reinstall.

I'm having fun figuring out how to modulate the new sound the snorkel offers. Drive like a commuter and it sounds stock. It's louder when you get on it, but not dramatically so. (Id already removed the charcoal filter in the airbox). The most distinct noise, though, doesn't seem to be based on revs, but throttle position. With deep or WOT, you get a deep bass note, resonant enough to vibrate your seat. As the revs climb, the bass fades out, fairly abruptly (around 5k rpm?). I don't mind that, for lack of a better phrase, nonlinearity, but its worth noting. Some may find the bass note boomy, but it doesn't bother me, especially considering I don't have to hear it during my commute if I don't want to.
