5 of 5 Wake up your Fiesta September 14, 2020
Reviewer: Hector C. from Villa Park, Illinois  
As per usual with Mountune parts, they fit great, comes complete with everything you need, and great instructions with color pictures make for an easy install. Car woke up a little more with this airbox. Definitely more responsive and smooth with a great sound without being over powering. Another great part from Mountune.

5 of 5 Mountune Induction System Upgrade November 13, 2019
Reviewer: Jesus Saenz from Mirama, FL United States  
Once you fit it in, and the instructions are very simple and easy to understand, the driving experience is enhanced immediately! When trying to fit the snorkel into the mountune induction box make sure to use a small amount of lubricant to ensure it fits in well without damaging the rubber or you'll risk an air leak. I am excited to continue with this company to enhance my vehicle's performance. My FiST is not more and more like a party on the road than ever before. Mountune's engineering is superb.

4 of 5 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.

4 of 5 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.
