JMA STG 3 Power Builder Package 2015-2021 STI

We have put together a package of dyno proven parts so you don’t have to find all the parts individually to reach your power goals.

With a proper tune all of these parts combined can net you an impressive 80 HP or 40% increase in peak HP and 120 FtLbs or 60% gain in TQ over stock! This package is what you are looking for if you want to make you 370+HP to the wheels (results require the use of ethanol fuel).
