2017 intake manifold
I saw one for sale on subispeed the other day, wondered if anyone had tryed one on 2013+ see how much better it is. http://www.subispeed.com/2013-subaru...6#.WA4jM-grKUk

That said, unless you try each part separately (intake manifold, exhaust manifold, stock tune), it's really hard to figure out where the individual gains are. |

They are showing WHP which can be increased by a pile of things. There were so many small changes made to the engine that to be able to say the manifold does X is impossible. Especially since any number you get will be well below the margin of error in the dyno in the first place. Dynos can easily show a variation of 10 or more HP with the exact same car on the exact same day. They are not precision instruments. |
I'm seeing a one WHP gain there in those dyno graphs..... a 2 wtq gain.... that is well within the change tolerance between dyno runs. It is hard to say that is because of the intake manifold or a change in temperature, or any slight variance in between.
@celek - I have followed your NA build, and you say you're a believer, can you state why? |

I think celek was saying that anyone looking to increase the redline via a tune would do well to run the newer intake manifold. Not that the manifold itself is responsible for the increasing redline. Ultimately, I don't spend enough time in that RPM range to bother investing money into it. |

Most of the graph shows nothing outside of tolerances in the machines. It's the last 500 rpm where things start to get interesting. No REALLY interesting, but interesting nonetheless. |

The cost vs improvement alone would make it a very poor mod if looking for better performance. |
