Air straightener like OE.
MAF in about the same location.
Gentle bend into throttle body.
I was disappointed with the (lack of) connection between the snorkel and the air box. As stated in the instructions, it is difficult to get the snorkel into the airbox. Unfortunately, once I got them together, there was nothing to keep them together. When inserting the filter (which is also fairly difficult), it pushed out the snorkel. If GrimmSpeed does a 2.0, perhaps some sort of flange like the OE could be incorporated.
Best. Decision. Ever.
Look, if you are thinking about adding a CAI to your BRZ (or FRS/86), get this GrimmSpeed masterpiece. I had been thinking about doing this minor modification for some time, and after much research I found this one. While many might offer similar gains as the GS product, the engineering team at GrimmSpeed designed theirs with the MAF A/F ratios in mind. Because it so closely mimics the factory settings, you won't have any CELs to deal with.
And if you think the CAI is awesome by itself, Shiv at OpenFlash Performance has made a dedicated tune to help the intake do its job even better. I kid you not when I say that those two minor tweaks has made my BRZ feel like a different car. The power band is much more linear and when the car gets above 4K RPM it has the most awesome growl.
The install took me just a bit over an hour and the step-by-step instructions provided with pictures make it a breeze. I can't think of an easier way to improve the performance of the BRZ/FRS while still keeping it NA. Buy this and install it. You won't be disappointed!
