Subaru Fuel System Package + Flex Fuel STI 2008-2019 is rated 4.4 out of 5 by 14.
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 Great Pump, fit perfect, works great I have had my AEM pump now for about 3 months, along with the full COBB Stage 3 setup. This pump was 100% drop in and go, no splicing needed, no issues, I thought about DW but heard 100 stories of them failing, then thought Walbro but heard they are loud! Went with AEM and will stick here through Flex Fuel soon, love this pump!

Rated 5 out of 5 by from My first Cobb product I bought this pump to cure my problem with hesitation at higher revs when using the sport or sport sharp settings. Bought a filter too to complete the service. Everything was very accessible, gotta love Subaru's. Pump fit perfectly, the only issue was the retainer ring for the pre filter was touch too small. Guy things to work eventually. Thanks Cobb for great tech support and awesome products. Fell back in love with my car during my test run.

Rated 5 out of 5 by from best of both worlds great product if even if you dont have e85 in your area as you can run 93 oct as well and if come across of get e85 in your area just fill it up and your good to go no more switching maps or running out of fuel to fill up with either

Rated 5 out of 5 by from flex kit Bought the full flex kit minus the sensor as I found a cheap one on ebay. Everything worked good for about 1 month before the non Cobb flex sensor took a dive. That's what I get for being cheap. Bought the Cobb flex sensor and just wish that's what i would have started with. After tuning I am almost 100hp over stock with E 85 and the supporting mods including turbo back exhaust and intake.

Rated 4 out of 5 by from Almost 5 stars As most of you probably know this 2.5 engine (at least on the 15 model) has an absurd amount of unnecessary "things". The worst part of this install was taking the manifold off to change rails and injectors. Not terrible but definitely more to it than say an I4 engine. But as far as the actual parts from cobb they are fantastic! The cobb parts actually went together easier than the factory parts removed. All neccessary parts were supplied in excellent packaging. If you want some cobb stickers just order this kit and you will be set for life lol. Two stickers in EVERY box (great job cobb on not being stingy!) We had one issue. As we were priming the fuel system we noticed fuel spraying everywhere. There was a tiny hole in the fuel hose fitting on the rear passenger side. Cobb was later contacted and they decided to next day air us another one at no charge (great customer service). Installed new line and no more leaks were found yay! Moving forward we finally got to crank the car. Ran good and smooth. One check engine light was on and it was for the pcv valve and it was keeping the car in limp mode. We connected the fuel pressure sensor that came with the kit to the pcv wiring plug. Not sure why it was throwing this code or if it has anything to do with the tune or not. We tried the different OTS maps on the accessport and same code still there. Could not clear. Disconnected the cobb sensor harness and reconnected those wires back to the factory setup. No more code. If I could find out why this code was being thrown it would be nice but honestly the car seems to be running smooth with no problems, no hiccups. Very satisfied with this kit! P.S. Wish the instructions were a little more clear. Only reason for not getting 5 stars is the check light for the pcv and instructions could be a bit more clear.
