Easy install. Rear fittings can be hard to get at but once you do your past the hardest part. Works great, low rpm stumble is gone!

Low RPM Jitter & Stumble Fix

I am still in the process of tuning my 14' STI but even with the 1st couple revisions I can feel consistent power in the 1.5k-2.5k RPM range. It used to get engine stumble below 2k rpm but now i can get as low as 1.5k without feeling jitters.
