The SPDZ1 3.0″ High-Flow Turbo Inlet Hose is engineered specifically for the 2015–2021 Subaru WRX with the FA20DIT engine, replacing the restrictive factory inlet pipe that limits airflow and performance.

Designed with smooth, gradual bends and a smooth internal finish, this larger-diameter inlet hose improves airflow consistency to the turbocharger, helping increase throttle response, reduce turbo lag, and improve overall intake efficiency. By eliminating the uneven airflow and weak points found in the OEM pipe, the SPDZ1 inlet hose also helps reduce the risk of vacuum leaks under boost.

Constructed from high-quality silicone with internal wire reinforcement, this hose is built to withstand heat, pressure, and long-term use far better than the factory unit. A precision CNC-machined flange adapter and OEM-style O-ring seal ensure a leak-free connection to the stock turbo inlet flange, delivering OEM-level fitment with performance-focused improvements.

Finished in SPDZ1 Red, this turbo inlet hose adds a clean, aggressive look to the engine bay while delivering functional performance gains for stock and modified WRX setups.
