Really Great Intake Kit July 25, 2019
Reviewer: Hunter from Fort Lauderdale, FL  
This intake kit is really really great, you can feel the slight increase in power, but more so with the torque (especially in sport traction control). I imagine that with the tune this product will really shine. It took about 2-2.5 hours to install with only a few hiccups. The instructions included are really helpful, but the video on Youtube by Adam Rainey really helps quite a bit. A few things to mention is fitting the stock snorkel to the Mountune Airbox is extremely difficult. You have to fiddle with the angle of entry into the box without tearing the rubber/plastic flange. Be patient with it. Also, the instructions don't tell you what to do with the included zip-tie. Once you get the extra pipe in place, zip-tie it to a solid surface nearby, like what I think is an intercooler charge pipe. Hope my review helps out you DIYer's, Really great and useful product.

Induction upgrade March 28, 2019
Reviewer: David Napoleon from Lake Zurich, IL United States  
Everything looked pretty good, install was about to be a breeze except for one flaw.  The plastic ears that hold the snorkel to the air box was just about impossible to disconnect, then impossible to install into new airbox, no matter what angles you put on it.  I had to grind down the ears on the snorkel in order to Heman the part inside the oval shapped hole.   My arms were sore for 2 days afterwards.

Well built, plug and play install March 9, 2019
Reviewer: Ian K from Space Coast, FL  
Another quality product from Mountune.  Air box was shipped securely.  Installation was a bit tricky with the OEM front air tube attaching to the air box.  Also, I found it easier to install the feed hose to the box, then lower the box into position.  Can definitely hear more intake sound and the car breathes much easier than before.  Recommend this addition...

Air Temp Over Sound December 13, 2018
Reviewer: Eric from Richmond VA  
If you want a well engineered high quality air box, look no further. I'll sacrifice sound for performance. My only beef with the install is fitting the OEM snorkel into the MT air box. Best to do with 2 people. Install was a breeze if you watch any YouTube video that will cover the headlight removal and airhose placement. This product is really tuned focused on air flow increase and consuming cold air based on the intake placement compared to the turbo location. Would easily be a 5 star product if not for the snorkel fitment.
