The Velossa Tech BIG MOUTH Ram Air Intake Snorkel for your 2015-2021 Subaru WRX and STI is the go-to mod for a boost in performance that complements the added aggressive look.

The BIG MOUTH is strategically designed to bolt directly onto your inlet cowl where air pressure recovery can be maximized and directly feed your current aftermarket or stock airbox with higher pressure air. It is the same concept as driving below sea level where the air pressure is higher, except you are able to generate higher inlet pressures with a properly designed ram duct. Increasing the inlet absolute pressure to your engine has profound effects on performance such as increases in mass air flow, reduction in wastegate duty cycle for turbo vehicles, and reduced inlet and charge temps. On top of all that awesome performance comes the BIG MOUTH growl and sinister stare, it sounds and looks great!

Designed in-house right here in the USA with the latest aerospace flow path engineering and design techniques, and backed by hours and hours of R&D, fitment testing and real world driving, we are sure you will fall in love with American made quality and engineering.
