The MAF sensor pipe and associated ECU tune offered by Frankenstein Motorworks is one of the best things you can do to make your 2GR swap run as it should. As explained in my blog post on the subject it keeps fuel trims nearly perfect and makes a few extra HP as well. However, in order to use it on your swapped 2GR an elbow with a connection for the PCV system is required, and a bracket to support the intake is strongly recommended.
This aluminum elbow and bracket takes care of the custom portion of the intake. You will need two 3" silicone couplers and four hose clamps to complete your intake.
