IBR Bolt-On BRZ Manifold Kit Subaru WRX 2015-2021 FA20DIT - Race Applications Only
IBR-BRZ-MANI-R
The iBR BRZ Manifold Kit for the 2015-2021 WRX platform is a complete complete kit to bolt on a BRZ or FRS intake manifold in a forward facing configuration. The BRZ manifold is a much better design than the original WRX manifold. It has larger runners, better flow and can be purchased in black plastic or a wrinkle red aluminum version.
One of the big benefits to the BRZ manifold is the port injection provisions along with an already existing aftermarket support for fuel rails, injectors and other accessories. This kit is designed to get many of the benefits of an aftermarket intake manifold but with a much lower cost and great OEM level support. Included in the kit are brackets to block off the BRZ port injection locations as well as all necessary hardware for the install.
OEM Intake Manifold and matching seal rings not Included. Misc vacuum hoses and fittings will need to be used depending on your AOS and other mods. Professional installation and tuning is highly recommended.
The manifold bolt-on kit is designed to bolt the BRZ or FRS manifold onto the FA20DIT (2015-2021 WRX) engine. The factory WRX manifold has a few weak points that this kit aims to fix. First, is restriction in the manifold itself. The BRZ manifold has larger runners, better flow distribution and a straighter flow path. Another benefit of the BRZ manifold is the ease of adding secondary injection to the intake manifold. The OEM injection ports on the BRZ manifold allow you to add a set of port injectors with an already existing aftermarket support.
