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, They're proud to introduce the all new GrimmSpeed Aluminum Turbo Inlets.\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eWHAT'S NEW FOR VERSION 2?\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe only difference between GrimmSpeed's original cast turbo inlets and the new Version 2 is that there are no longer two different fitmentts for the 2015-16 and 2017-21 fitmentts. 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.\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eDEVELOPMENT\/FLOW:\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003eFor the development of The GrimmSpeed Turbo Inlet, they channeled their knowledge of intake and post MAF hose creation to bring you the best-designed and best-flowing piece possible. They began with laser-scanning the area and using their Faro Arm to pinpoint exactly how much room they had to play with during the design process. This not only ensured perfect theoretical fitmentt, but also allowed GrimmSpeed 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:\u003c\/p\u003e\n\u003ch3 dir=\"ltr\" data-mce-fragment=\"1\"\u003e\u003cspan style=\"font-size: 1em;\" data-mce-fragment=\"1\"\u003eQUICK SPECS:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\n\u003cstrong data-mce-fragment=\"1\"\u003eA380 Cast Aluminum\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e- Extremely durable, eliminates OEM inlet cracking issues\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\n\u003cstrong data-mce-fragment=\"1\"\u003eCNC Machined\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e- For perfect fit and sealing surfaces\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\n\u003cstrong data-mce-fragment=\"1\"\u003eOEM Fitment\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e- Easy install, no modification required\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\n\u003cstrong data-mce-fragment=\"1\"\u003eSeamless Flow\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e- CAD optimized design eliminates OEM air pockets\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\n\u003cstrong data-mce-fragment=\"1\"\u003eHigh Quality Breeze Clamps and Viton O-ring\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e- Included in every kit\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\n\u003cstrong data-mce-fragment=\"1\"\u003eNo Tuning Required\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e- Even when coupled with GrimmSpeed DRY-CON Panel Air Filter and Post MAF Hoses for maximum performance\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\n\u003cstrong data-mce-fragment=\"1\"\u003e*Install Note* -\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003c\/strong\u003eThe GrimmSpeed Turbo Inlet is designed to interface perfectly with the\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003cstrong data-mce-fragment=\"1\"\u003eGrimmSpeed Electronic Boost Control Solenoid for the 2015-21 WRX\u003c\/strong\u003e.
