COBB Tuning Stage 1+ Power Package | 2015-2018 Subaru STI (616X01P)

This is an amazing product from Cobb, the stage 1+ kit with the tune does give you a sizable gain in power especially in the mid range. Do be careful of boost creep and read the map notes on Cobb’s website and everything should go well for you.

First mod for any STI should be the Cobb AP. With the stage 1+ package you get that and then some. The AP unlocks the potential in your stock vehicle and the intake gives it a nice soundtrack of turbo noises (not much power though). Love it would buy again no doubt.
Super easy install both intake and uploading AP maps as well. Shout out to MA perfomance they got me my order extremely fast.

I am hesitant to make any changes to my vehicles and I’m very glad I decided to install the stage 1+ package. Couldn’t be more satisfied with this product.

Not significant but still noticeable performance gains. I should have purchased the Cobb Stage 1+ Power Package as the first mod - very satisfied. It’s like driving a totally different car; shifting through gears how it’s supposed to. The Cobb SF intake sounds amazing. Install was easy with both the intake & loading OTS maps using the Cobb Accessport. I enjoyed driving my stock STI but just a little more these days on Stage 1+.

I'm sure all of us are excited when we finally pull the trigger on car parts. This has got to be the most bang for your buck product combinations on the market. Not only are gains immediately noticeable, it only took about 35 minutes for me to finish installation. It sounds INCREDIBLE and feels great too. HIGHLY RECOMMEND
