GR Corolla & GR Yaris Billet Intake Manifold

[@alberttsai3659]

Do have you any dyno comparisons vs the stock intake manifold on a stock turbo that you can show us?

[@IchibanEngineering]

this is usually used on a upgraded turbo, and for those who are looking to push high HP numbers. Is like putting a large intercooler pipe on a small turbo. There is no sense in that.

Is a tune required after install?

[@IchibanEngineering]

yes of course.
