The built-in velocity stack creates a smooth transition from the large filter area to the turbo inlet. This motorsport design offers excellent laminar properties resulting in a very high inertia flow with reduced drag and power-robbing turbulence.

Our intake airbox is designed to accept our cast turbo inlet pipe to increase airflow over stock from 24% (intake only) up to 50.4% combined! Adding a turbo inlet further reduces significant air restrictions while maintaining the largest size possible from the airbox to the turbocharger.

Turbo inlet pipe is an optional upgrade and can be purchased with your intake or added at a later date.

The intake and turbo inlet combo makes upgrading to a hybrid turbo a simple bolt-in job. CNC-machined and o ring sealed adapter rings fit the stock or a variety of aftermarket turbos without hassle. The turbo inlet continually adapts to the turbo to not introduce any restrictions and maintain the largest size possible when upgrading turbos.

Hybrid turbo adapter rings are sold separately from the turbo inlet upgrade.

Multiple air supply avenues are used to guarantee airflow for any power level. High-pressure flow from the grille directly provides a ram air supply to the filter. If additional air demands are required, the intake will pull low-pressure air through the filter plate louvers as needed. This dual-zone design ensures your intake will never be a power limitation for even the most extreme builds.

Your stock airbox is manufactured under regulations to perform only one job; mute all engine and turbo sound at any performance cost. Your new IE poly intake system will release the sweet sounds of turbo spool, engine throttle, and diverter blow-off that your S-class SUV deserves.

3D scanning tools are leveraged to create a high-resolution digital environment allowing our engineers to take advantage of all available space for a complete performance design while ensuring a hassle-free install.

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 an intake system with power gains of up to 19WHP and 21ft-lbs of torque, with even higher gains possible on hybrid turbo setups!  

The proof is in the testing. Back-to-back flow bench results show constant and consistent CFM gains of up to 50.4% CFM over stock! This increase in flow details the intake design's efficiency over the factory parts and capability to provide any required airflow demands from ECU tunes and hybrid turbocharger upgrades.

The following report details the above graph proving the efficiency gain of our performance intake system on the stock turbo.

Upgrading to a hybrid turbocharger demands even more airflow. This flow result represent IE’s intake and inlet upgrades with a hybrid turbo.
