Subaru Stage 3 + Flex Fuel Power Package Titanium STI Sedan 2011-2014 is rated 4.7 out of 5 by 372.
Rated 5 out of 5 by from Just do it. I purchased the Ap about a week ago for my 2014 wrx hatch. I have an invadia cat back exhaust, but that is all the mods i have done so far. Install was easy. Right off the bat I noticed that the car ran so much smoother. This is the way it should of come from the factory. I did notice that there was more power and the car just wanted to pull. Amazing. Cobb truely makes a great product. My wrx hwd 8500 miles at install time. Should of done it a while ago. Currently running stage 1 93 octane map. I purchased my ap from Flat Four specialties, but I did speak with cobb directly qnd they were very helpful wnd answered my questions.

Rated 5 out of 5 by from Must get for a first mod! You won't be disappointed. I recently purchased the AP V3 as one of my first modification for my 08 STI. Before installing, I called COBB because I had some questions and didn't want to install anything wrong just in case. And they basically said if I need help they will walk me through the entire process on the phone. I just asked a few questions and installing and flashing one of the OTS map was a breeze! The only downside is the 3M sticky tape on the mountt, fell off the first day. I recommend when placing the mount on your desire location, don't put any load on it for at least a whole day for it to fully adhere to the surface. Besides that, great product!

Rated 5 out of 5 by from Worth. Every.Penny! Just put this on my '13 WRX sedan with about 6500 miles on it. First thing I've done to it aside from tinting the windows, and… HOLY…WOW! I was a little concerned about noticing a difference due to not having upgraded the exhaust, air intake, etc., but there is a HUGE difference. A serious kudos to COBB for not only putting out a darn good product, but for engineering it to be so incredibly simple to install. Even the COBB website is packed full of relevant and useful information. I'll never think about entertaining any other company to do business with: these guys take their entire company very serious - HIGHLY recommend looking no further than here. Finally, I NEVER send a review for something I bought, but COBB truly EARNED the effort to send this.

Rated 5 out of 5 by from a MUST buy product! this is a MUST buy product even if you plan on keeping your car completely stock. If you mod your car its a necessity! I installed mine last night with no mods on the car. just the stage 1 map for 93 octane. I noticed a difference IMMEDIATELY.. the car runs and pulls like so smooth and strong! no more boost lags or flat spot in the 5-6k rpm range.. This car seriously needs this and honestly should have come from the factory this way. THANK YOU COBB for doing what you do! I got the stage 1 package so i will be installing the intake tonight and cant wait for the results : )

Rated 2 out of 5 by from Cobb Ethanol Sensor The sensor lasted for about 14 months before total failure. I ordered the replacement flex fuel sensor from COBB. Upon receiving the sensor I realized that COBB had just sold me an $80 ethanol sensor made by Continental for $250+. I returned the sensor and ordered on off of AMAZON for $86. Work just as well. And since the one COBB provided me with my kit took a dump after a year I figured whats the harm in ordering the same unit from amazon and adding a $10 2 year protection plan. Unit worked perfectly.

Rated 5 out of 5 by from Another quality cobb upgrade Great addition to my 09 wrx 5 door. Very noticeable increase in torque and boost just as the graphs show. This was my latest upgrade in addition to the cobb sf intake and SPT cat back exhaust. install : all in all it took me about 3 hours and I did it solo - would definitely take less with a helper. The install video is pretty on point. I would definitely replace the 'donut' gasket, my car only has 55k miles on it and the old gasket was rusted/gunked into the old dp... I chiseled it off and the thing was a mess, so I took the gf's car to the local dealer and bought a replacement. I also replaced the springbolts where the dp and mid pipe connect, mine were pretty rusted and one of the springs actually broke when I took it off.

Rated 5 out of 5 by from Awesome product Me and my buddy put this on and it took us about 5 hours of partially goofing around and such. For the 2016 STI it is nearly impossible to get to the turbo heatshield / downpipe without taking off the intercooler. I am currently running a Muffler Delete Axle Back system ontop of this, and it sounds awesome. It is deep and has a nice rumble. The major difference I noticed between Stage 1+ and Stage 2 is that boost hits and holds 17-18lbs at 4000 rpms in stage 1+, but in Stage 2 it hits around 10lbs at 3500-4000 and then starts building but is way torque-ier. Over all, awesome product and I recommend it if you are looking for a little extra kick

Rated 5 out of 5 by from Awesome Product - 2015 STI Prior to installing the intake the car was 100% stock. Installation is super easy (30 mins) and requires only the simplest of tools. After installation I downloaded the 15 STI 91+map from the website and uploaded it to the car. I highly recommend this combo to anyone feeling like the car deserves a bit more power. I was surprised to find the car pulls noticeably harder and sounds amazing. The intake is loud so if you don't want to hear the turbo/wastegate keep the stock intake and just flash to stage 1. I went 91 tune although I run 93 octane to stay on the slightly safer side. Great products!
