The Mishimoto Silicone Airbox Hose Kit for 2015+ Subaru WRX includes the upper and lower engine airbox hoses as direct-fit replacements. Both hoses are crafted from four layers of silicone with heat-resistant embedded fibers and feature smooth internal surfaces to promote improved airflow versus accordion-style factory pieces. Designed to resist oil particle degradation and improve pressure and heat tolerance, the kit is offered in black, blue or red and includes a Lifetime Warranty.
