Product Description

The PERRIN PSP-INT-350RD Red Afta-MAF Intake Tube is a direct replacement silicone intake hose designed for turbocharged **2002-2007 Subaru WRX and 2004-2007 WRX STI** models. It replaces the stock corrugated rubber hose connecting the inlet and air box with a smooth-bore, high-flow silicone tube. This design promotes more efficient airflow, helping reduce turbo lag and improve throttle response without requiring ECU tuning.

Constructed from durable multi-layer silicone and finished in a vibrant red, this intake tube not only enhances performance characteristics but also improves engine bay visuals. The included clamps ensure a secure, worry-free installation that typically takes about **10 minutes** with basic hand tools. Particularly popular for replacing brittle or cracked stock hoses on older WRX/STI builds, the Afta-MAF tube is a straightforward and cost-effective way to refresh your induction system.
