Introducing the Velossa Tech 2023+ Toyota GR Corolla BIG MOUTH Ram Air Intake Snorkel. 

This kit maximizes your OEM airbox and virtually any aftermarket intake system, and is a simple bolt-on that compliments your GR both aesthetically and performance-wise. We have tested this product extensively, on the road for real world results.

The GR Corolla BIG MOUTH intake design is a first for us, as it is a dual feed intake that uses the OEM opening as an air feed as well as a separate high pressure feed below it.

This BIG MOUTH will fit your completely stock intake box; if you would like to replace the OEM feed tube with our higher-performing induction system, please order the BIG MOUTH Ram Air Intake Snorkel PLUS High Flow Induction.

If you have an aftermarket intake such as SXTH airbox, all you need is the BIG MOUTH snorkel, you will not need the high flow induction system.


Before and after logs on a 2023+ GR Corolla at 89 degree ambient temperature with basic bolt-ons, the only variable changed was the Velossa Tech BIG MOUTH Ram Air Intake between runs.

Our NEW Generation 4 BIG MOUTH Ram Air Intake Snorkels feature removable flare/inlets and allows you to truly customize your intake in ways never before seen!

If you'd like to really get wild, check out our Diode Dynamics integrated BIG MOUTH "LIT KIT", this is a world first! 

For even more performance improvements and to maximize your OEM airbox, check out our BIG MOUTH Ram Air Intake Snorkel PLUS High Flow Induction kit!

With ease of removing the flare by unscrewing 4 set screws, you can change the color of your BIG MOUTH to get the look that fits your self-expression. Generation 4 is a patent-pending feature that will change the way we present our cars to the world, Velossa Tech is proud to be able to offer this new innovative feature. Being able to replace a flare with ease is now a reality. Replacing flares is not just easy, but affordable!

The BIG MOUTH was developed for better overall mass air flow for stock, tuned cars or highly modified engines, you also have ability to customize the color of the inlet flare and body. This is truly a unique piece in that it allows you to get the performance benefits of a properly engineered ram duct and have the aesthetic appeal of your liking!!

It will bolt right directly on to the inlet cowl and feed your aftermarket or stock airbox on your 2023+ Toyota GR Corolla, in fact it will greatly improve the performance of your stock or aftermarket intake setup.

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.

As a car moves through the air, the air pressure directly in front of the bumper increases with the square of speed. The BIG MOUTH is strategically designed and positioned for maximum air pressure recovery. Basically, it feeds your current intake 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 such as the BIG MOUTH.

Increasing the inlet absolute pressure to your engine has profound effects on performance. Increases in air mass flow, reduction in wastegate duty cycle (for turbo vehicles) and reduced inlet and charge temps are some of the benefits of running a properly designed ram inlet. On top of all that awesome performance comes the BIG MOUTH growl and sinister stare, it sounds and looks great!


Want your 2023+ Toyota GR Corolla to stand out? The BIG MOUTH is the only ram air system for the 2023+ Toyota GR Corolla that allows you to choose from over 28 colors for either the body or the flare, giving you the added edge of customization, with hundreds of different variations possible.


Installation can be done with basic hand tools. We supply all straight forward color instructions (downloadable below), backed with our Customer Support email to help guide if any questions arise. All hardware is always included (if necessary) in our BIG MOUTH Ram Air kits.

NOTE: Rain or snow do not adversely affect the engine once a BIG MOUTH is installed.

When people see that massive inlet flare through the grille, they'll know it's Velossa Tech!
