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.

So much better

This beats oem out of the park it has better material and is much better than that plastic brittle oem one and is easy to put on and off of the car


Thank you for your 5 Star Review of the Grimmspeed Cast Aluminum Turbo Inlet for your WRX! It is great to hear that you found it to be an improvement over the OEM inlet and that it was easy to install. The cast aluminum construction is definitely a more durable and reliable material compared to the plastic OEM inlet. Enjoy the increased performance durability!

Great fitment. Great craftmanship. Highly recommend Grimspeed products.


Grimmspeed did it right with their Cast Aluminum Turbo Inlet! It provides better flow of air to your turbo providing better performance! It also replaces the brittle OEM plastic design that is prone to cracking and breaking which can cause a multitude of problems! Definitely the way to go! Thank you for your 5 Stars!

GrimmSpeed turbo inlet

This turbo inlet is the best on the market! Flawless construction paired with an easy installation make this much needed upgrade that much better. Glad I didn’t wait until the OEM failed to replace it!


Thank you for your 5 Star Review of the Grimmspeed Cast Aluminum Turbo Inlet! The OEM turbo inlet is known to crack and break creating a boost leak. The Grimmspeed Inlet is cast aluminum eliminating this issue while also creating a greater flow of air and better perfromance! No tuning is required with this easy install ensuring your WRX is running the way it should!

Must change on even a full oem car. The stock inlet is garbage and will fail you eventually. Save yourself some heart ache now and put this one on your wrx


The Grimmspeed Cast Aluminum Turbo Inlet is the perfect replacement of the brittle OEM design! It provides better airflow and reliability ensuring your engine stays healthy and at optimum performance! We appreciate your 5 Stars!
