GrimmSpeed 15-21 Subaru WRX Version 2 Aluminum Turbo Inlet

Engineered to prevent the common failure of OEM plastic inlets, the GrimmSpeed Version 2 Aluminum Turbo Inlet for 2015-21 WRX provides superior durability against cracking and separation. This critical upgrade eliminates the risk of brittle plastic deteriorating around the BPV and turbo flange, ensuring consistent metered airflow and protecting engine performance. Constructed from robust aluminum, this inlet delivers long-term reliability where the factory component typically fails.

Precision-engineered from A380 cast aluminum, this CNC-machined turbo inlet eliminates the common OEM cracking issues while maintaining perfect OEM fitment. The CAD-optimized design delivers seamless airflow by removing factory air pockets, and includes premium Breeze clamps and Viton O-ring for superior sealing. No tuning required when paired with GrimmSpeed components. Note that while designed to interface perfectly with GrimmSpeed Electronic Boost Control Solenoid, installation with OEM or other aftermarket BCS may require additional hardware for proper mounting.
