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.

GrimmSpeed’s ALL NEW Aluminum Turbo Inlets have a few advantages over stock:

Since each GrimmSpeed Inlet is cast from extremely strong A380 Aluminum, they’re not prone to fracturing or cracking like the factory piece is known to. That means this is the last turbo inlet you’ll put on your car; whether you’re planning to stay mostly stock, or are on track for a monster build. GrimmSpeed Inlets are precisely CNC-machined after casting, guaranteeing a perfect fit for your bypass valve, charge pipe, post MAF hose/intake, and boost controller with a better seal thanks to the deep groove for the supplied Viton O-ring. Not only are they made from superior material, but their design also makes for an easier install compared to stock.

QUICK SPECS:

• A380 Cast Aluminum – Extremely durable, eliminates OEM inlet cracking issues
• CNC Machined – For perfect fit and sealing surfaces
• OEM Fitment – Easy install, no modification required
• Seamless Flow – CAD optimized design eliminates OEM air pockets
• High-Quality Breeze Clamps and Viton O-ring – Included in every kit
• No Tuning Required – Even when coupled with GrimmSpeed DRY-CON Panel Air Filter and Post MAF Hoses for maximum performance

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.
