Subaru Accessport V3 (AP3-SUB-003) is rated 4.8 out of 5 by 209.
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 5 out of 5 by from Absolutely love this product I have a 2013 Subaru wrx and have had the access port for about a month now an I absolutely love it and all the features it provides. I also enjoy the different maps specified for the aftermarket components you have on it. Before I had just a down pipe on my car with no tune and once I got the access port my car was running much healthier and increased power a very noticeable amount. For everything that this access port can do it is absolutely worth the money, and recommend it to any one looking for a tune. The only issue I had with this product is the mounting beaker for it, the adhesive sticky part did not last a day the access port just kept falling down.

Rated 5 out of 5 by from Love It, Great Buy! Bought it for my 11 sti. Guy who sold it left tune on it, so it ran like sh**. Bought this and it came with two covers, COBB decal, USB cord, and mount. Car runs great. I like it because you can monitor EVERYTHING.

Rated 5 out of 5 by from The Keys to the Treasure Chest :) Purchased on 3/8/14 and couldn't be happier. Pros: Noticeable refined mapping from stock, higher revs, cleaner pull, better MPG. This is the beginning of my modding. My car drives better than stock map just with this upgrade. Cons: None, I should of purchased this sooner. Had my WRX since Dec/2012. I was hesitant but that has escaped my mind. Thank you COBB for this excellent product. Now currently thinking of Stage 2 :)

Rated 5 out of 5 by from V3 Access Port on 2014 WRX 5 Door Great product. Put on my 2014 WRX 5 door @ 19K miles. Have only done the Access Port but plan to do a down pipe in the near future. For my set up (stock intake and SPT cat back) there are 2 maps. 91/92 Octane and 93/94 Octane. Initially installed the 91/92 Map as my fuel tank was full of 92. A noticeable increase in performance. Ran that tank out and put in 93 and remapped. Even more performance. The car does runs smoother and it pulls much harder in second gear and up. Had a minor rookie issue trying to detach the AP cable from the ECU. Called Customer Service from my car. Got thru right away and actually talked to Cody from the videos. Super helpful and as nice on the phone as in the videos. Made me feel even better about my purchase. Looking forward to the down pipe and then possibly an air intake. Love the flexibility for the components!
