GrimmSpeed Aluminum Turbo Inlet

New and Improved

Development/Flow

For the development of The GrimmSpeed Turbo Inlet, GrimmSpeed channeled our knowledge of intake and post MAF hose creation to bring you the best-designed and best-flowing piece possible. GrimmSpeed began with laser-scanning the area and using our Faro Arm to pinpoint exactly how much room they 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.
