Customer Reviews
Easy to install and works like it should. No more stumble after 2800rpm
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!
Highly recommend and easy to install
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.
Easy install, good quality
