Carbon Fiber — More Than Style
Carbon fiber lets IE's engineers create complex shapes and angles to maximize internal volume while maintaining high resistance to heat. This design practice utilizes every millimeter available in the engine bay, providing a much larger air supply and smoother flow.
Seamless Design
This unique 1-piece airbox design offers a seamless, beautiful look without the chance of air leaks, finicky installation, rubbing noises, or parts working loose over time — all common with multi-piece airbox designs.
Built-In Velocity Stack
The built-in velocity stack smoothly reduces airflow from the massive 5" air filter down to the turbo inlet with excellent laminar properties, creating a very high inertia flow from the huge filter with very low drag or power-robbing turbulence.
Optional Turbo Inlet
Upgrading your intake with an IE cast turbo inlet further removes airflow restrictions and maintains the largest size possible from the intake to the turbocharger — increasing flow from 28% (intake only) up to 57.6% over the stock intake and turbo inlet. The turbo inlet pipe is an optional upgrade, purchasable with your intake or added later.
Hybrid Turbo Ready
Your IE SQ5 intake and turbo inlet make upgrading to a hybrid turbo a simple bolt-in job. The cast turbo inlet design uses CNC-machined, o-ring-sealed adapter rings to fit either the stock or a variety of aftermarket turbos without hassle, always adapting down to the turbo to avoid restrictions and maintain the largest size possible. Hybrid turbo adapter rings are sold separately from the turbo inlet upgrade.
Multiple Pressure Zones
The intake takes advantage of multiple air supply avenues to support any power level. The front large air inlet receives outside high-pressure flow from the front of the grille, acting as a ram air design for most of the supply, while filter plate louvers pull extra air from the low-pressure zone underneath. These dual zones ensure a free air supply across the entire filter, so your intake never limits even the most extreme builds.
Unique Sound
Your sporty SUV is equipped with a 6-cylinder turbocharged engine — sound like one. The factory airbox is designed to mute all engine and turbo sounds. Upgrade to an IE intake system and you'll instantly become addicted to the new turbocharger spool, engine throttle, and diverter valve symphony under the hood. Your SQ5 won't just pull harder, it'll sound classy, refined, and powerful.
Precision Fit
3D scanning tools create a digital duplicate of the vehicle's engine bay, grille, bumper, and hood. These high-resolution scans give IE's engineers a digital environment to take full advantage of all available space while ensuring a perfect fit.
Power Results
Every inch of IE's intake system evolved from countless design revisions, rapid prototyping, flow bench testing, dyno runs, and real-world verification to maximize airflow and performance — the result is up to 19 WHP and 21 ft-lbs of torque, with even higher gains possible on hybrid turbo setups.
Back-to-back flow bench results show constant, consistent CFM gains of up to 44.2% over stock, detailing the intake design's efficiency over factory parts and its capability to meet any airflow demand from ECU tunes and hybrid turbocharger upgrades.
Flow Report — Stock Turbo
| -In. H20 | Stock Intake | IE Intake & Stock Inlet | IE Intake & IE Inlet |
|---|---|---|---|
| -5 | 129 CFM | 165 CFM | 186 CFM |
| -10 | 198 CFM | 236 CFM | 268 CFM |
| -15 | 250 CFM | 292 CFM | 333 CFM |
