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.

Resonators are currently out of stock. I recommend getting one from Toyota along with any other OEM parts you need for your swap. PN 17893-0P090

This custom silicone elbow provides both the port for the PCV and also a port for the OEM resonator from the Sienna (pn: 17893-0P090). The resonator significantly improves the quality of the data provided by the MAF sensor, allowing the ECU to make better load calculations resulting in more consistent air fuel ratios and generally making the engine run just a little bit better. The resonator can be purchased brand new from Toyota for about $25. If you do not intend to use the resonator you will need to supply your own plug for the resonator port.

This kit includes a bracket to support the intake as shown below (compatible with the E153 and E35x transmissions, may work with others if they have a threaded hole in the same location), plus the necessary clamps and hardware.

Fits the 3.5" MAF pipe from Frankenstein Motorworks. Available for both the stock 70mm throttle body as well as the 76mm throttle from the 3UR-FE v8.

Resonator Effects

Commonly assumed to be only for noise suppression, my testing has shown that the Helmholtz resonator often found between the MAF sensor and the throttle body on OEM intakes actually has a significant smoothing effect on the data from the MAF sensor. Since this is one of the primary inputs from which the ECU determines everything else, getting the best possible MAF data is very important. The graph below shows the difference in MAF data from two pulls with the resonator vs two pulls without the resonator.

This in turn allows the ECU to produce a smoother load curve, and in some cases results in a smoother more consistent air fuel ratio. While I have not yet found this to result in more power, it certainly can't hurt to provide the ECU with better data.
