PERRIN Performance PSP-INT-350BK Afta-MAF Intake Tube Black

The PERRIN Performance Afta-MAF Intake Tube is a direct replacement for the factory corrugated rubber hose between the inlet tube and air box on 2002-2007 Subaru WRX and STI models. This high-quality black silicone intake tube creates smooth, even airflow while adding a performance look under your hood.

Key Features:

• Perfectly smooth internal surface with larger diameter than OEM part for improved airflow
• Replaces factory corrugated rubber hose that becomes hard, brittle, and prone to cracks over time
• Increases horsepower and torque without requiring ECU tuning or recalibration
• Proper MAF alignment and plumbing size maintains correct air-fuel ratios and prevents check engine lights
• Constructed from durable black silicone for long-lasting performance
• Ideal for restoring high mileage or older WRX, STI, and Legacy GT models

This intake tube is designed and tested to work safely on your vehicle without any tuning required, though additional power gains are possible with proper ECU tuning. The smooth internal construction reduces turbulence and allows for more efficient air delivery to your engine while the enhanced airflow lets you hear turbo spooling and blow-off valve operation more clearly.
