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.

Good upgrade, well made. August 21, 2018
Reviewer: Randall W from New Albany, OH United States  
I already had the Accessport with tune, RMM and high-flow air filter. This might have improved the sound a little bit, but the biggest difference was where the power hits. There is definitely more high-rpm power, which comes from upping to almost 215 HP (MP215). Just need the High Flow Induction Hose once they make one for the '17. Finding a spot for the secondary inlet is a bit tricky. The kit comes with a zip tie to hold it in place - mine is pretty much on top of the intercooler hose pulling from behind the bumper.

WHOOSH September 18, 2017
Reviewer: Brandon McCann from Colorado Springs, CO United States  
Installed this after the quick shift, and it was a breeze in comparison. Took me about 45 minutes total to remove the stock components, line everything up, double check, fix the tubing when it wasn't properly secured, and finish it off. You can tell the quality of the pieces and the fitment/engineering is top notch, as everything I've received from Mountune tends to be.

The biggest change with this upgrade was the extra turbo noises, and you can't go wrong there. I'm sure the intake temps were a bit cooler and the throttle a bit more responsive with this piece alone, but I also installed an Accessport right after, so I couldn't tell you exactly how big the difference was. In any case, fully recommend this upgrade for your ST; you will not regret it.
