Don't risk cracking your OE plastic inlet.
One of the biggest complaints we’ve heard from 2015-21 WRX owners has to do with cracks forming in their OEM plastic turbo inlets from removal, installation or just general wear and tear. As the plastic inlet ages and becomes brittle, it has a tendency to separate around the BPV and/or turbo flange portion of the piece. Since the inlet is one of the most critical components for metered air and consistent performance, cracks or separation can lead to dangerous conditions for the engine. To solve this problem before it happens, we’re proud to introduce the all new GrimmSpeed Aluminum Turbo Inlets.
WHAT'S NEW FOR VERSION 2?
The only difference between our original cast turbo inlets and the new Version 2 is that there are no longer two different fitments for the 2015-16 and 2017-21 fitments. Now they are both covered in one kit with interchangeable threaded fittings to perfectly fit the PCV return line on either the earlier or later models. Other than that, all of the features are identical to the version 1.
DEVELOPMENT/FLOW:
For the development of The GrimmSpeed Turbo Inlet, we channeled our knowledge of intake and post MAF hose creation to bring you the best-designed and best-flowing piece possible. We began with laser-scanning the area and using our Faro Arm to pinpoint exactly how much room we had to play with during the design process. This not only ensured perfect theoretical fitment, but also allowed us to 3D print multiple versions for real-world testing and confirmation, resulting in an optimized version of the inlet. That final version was able to eliminate the air pockets that impede flow in it's OEM counterpart and gave The GrimmSpeed Inlet superior flow characteristics:


Although the inlet itself isn't meant to net huge gains as a standalone upgrade, it is an essential part of upgrading the intake tract and facilitating the ability for your engine to flow more freely. Best of all, The GrimmSpeed Cast Aluminum Inlet will ensure that you won't ever put your engine in jeopardy due to a crack and resulting change in metered air.
