Injen 15-21 Subaru WRX 2.0L 4 Cyl. Wrinkle Black Cold Air Intake

The Injen SP1209WB is a high-performance short ram air intake system designed specifically for the 2015-2021 Subaru WRX 2.0L turbocharged engine. This wrinkle black finish intake replaces the restrictive factory airbox to deliver dyno-proven gains of +9 HP at 5000 RPM and +11 lb-ft torque at 4200 RPM while improving throttle response and engine sound. It fits all WRX Base, Premium, and Limited submodels with a direct bolt-on installation.

Key Features

  • Patented MR Technology: Includes removable restrictor rings to fine-tune airflow for optimal power across the entire RPM range on stock or modified engines
  • Wrinkle Black Powder Coat Finish: Heat-resistant and durable coating on 6061-T6 aluminum tubing protects against corrosion and complements engine bay aesthetics
  • High-Flow Conical Air Filter: SuperNano-Web dry filter media allows 31% more airflow than stock while being washable and reusable for long-term performance
  • Mandrel-Bent 3" Aluminum Piping: Smooth, uninterrupted airflow path reduces turbulence and pressure drop for maximum horsepower and torque
  • CAD-Engineered Precision Fit: 100% CAD-designed with TIG-welded construction ensures seamless integration without modifications
