Nice Upgrade! Worth it!!
Install went smoothly. Supercharger noise is definitely more noticeable and how it should have sounded from the factory!! Noticed a slight improvement in MPG as well as Boost P.S.I. Definitely worth the $$$ to improve the stock intake!

Happy after installation
I had every intention of leaving a bad review just because installation kinda sucks. Doesn't take very long but the way the top of the air box goes on is poorly designed. Tabs on rear side hit factory wire harness and make it frustrating to install. Not to mention I had to bend the angled plate below the filter just to make the filter fit on the lip of the tubing. BUT...after driving a few times it put a smile on my face. I had removed the intake turbo "silencers" for more noise long before this so I didn't anticipate any more turbo noise but there is definitely more turbo spool sound along with CAI sound. Might be a little more responsive and better mpg.

Get longer bolts
The bolts included are just a touch too short. Putting them in ended up stripping the threads. Had to rethread (so much fun) and install longer bolts. Keep in mind, these threads are plastic and strip pretty easily, so be careful with that lol. If it weren’t for that incredible experience, I’d give the product 5 stars.

Installed this because I kept getting a CEL after installing a cold air intake. Installed this, cleared the code and hasn’t come back since

Love the way it sounds you can definitely hear those turbos also install was pretty easy took about an hour to put in I do have to say they could add an O-ring for this map sensor

Great construction
This is a very well engineered intake. Very easy to put together and made of great materials. Great sound when at full throttle and can notice a difference in throttle response.
