Grimmspeed Aluminum Turbo Inlet – 2017–2021 Subaru WRX (USDM) | FA20DIT

Eliminate the restrictive factory plastic turbo inlet pipe on your 2017–2021 USDM Subaru WRX with the Grimmspeed Aluminum Turbo Inlet. The factory plastic inlet pipe is a known restriction point on the FA20DIT — its smaller diameter and less-than-ideal geometry limits airflow to the turbocharger, particularly on modified builds running increased boost. Grimmspeed's aluminum turbo inlet replaces the factory unit with a larger, smoother-flowing aluminum pipe engineered to maximize airflow to the turbo compressor inlet for improved spool response and power delivery.

Key Features

• Replaces Restrictive Factory Plastic Inlet: Eliminates the factory plastic turbo inlet pipe — a known airflow restriction on the FA20DIT platform — with a larger, smoother aluminum alternative
• Aluminum Construction: Durable aluminum construction for long-term heat resistance and reliability in the demanding turbo inlet environment
• Improved Turbo Spool & Airflow: Larger diameter and optimized geometry improves airflow to the turbo compressor inlet for improved spool response and power delivery, particularly on modified builds
• USDM WRX Specific: Engineered specifically for the 2017–2021 USDM Subaru WRX (VA) with the FA20DIT engine — not compatible with all markets
• Grimmspeed Quality: Manufactured by Grimmspeed — a trusted name in Subaru performance parts with a proven track record on the WRX and STI platforms
