Overview:

The HPS Silicone Air Intake Kit Post MAF Hose is a high-quality replacement for the restrictive OEM rubber air intake hose found on select Scion FR-S, Subaru BRZ, and Toyota 86 models. Designed for enthusiasts seeking improved throttle response and reliability, this kit enhances your vehicle’s intake system without requiring any tuning or modifications.

Constructed from durable, high-temperature reinforced silicone, this hose reduces heat soak and maintains efficient airflow through the factory air box and fresh air scoop. It’s an ideal upgrade for daily drivers and performance enthusiasts who want to restore proper engine idling and eliminate common vacuum leaks caused by aging OEM hoses.
