APR’s 4.0T EA825 V8 Intake System for SUV models provides an OEM+ appearance upgrade with a single-body carbon fiber intake plenum in a gorgeous matte forged carbon finish that flows up to 22% more than stock. Enhanced turbocharger inlets feature bell mouth profile into the factory turbocharger to promote flow and allow for easily upgrading turbos in the future. The system features a proprietary performance intake filter with a high flow cotton gauze filtration material and flow-bench optimized design that enhances airflow through the system and into the intake plenum. The filter flows up to 12% more than stock and sees reduced pressure drop at the same flow rates. This puts less strain on the turbochargers, and maximizes performance, all while sharpening throttle and turbocharger response. This is the ultimate intake for the 4.0T EA825 V8 engine!

The Design:

The 4.0T SUV’s engine bay design is tight. The factory utilizes a dual inlet design that feeds into an airbox placed under the intake filter cover which feeds into a multi part turbocharger plenum. Airflow is directed 180 degrees into turbo inlet adapters and into both turbochargers.

The intake filter was optimized on the flow bench to provide the maximum amount of flow while utilizing a filter media that provided adequate filtration and extended filter life. Through several design revisions verified on the flow bench, APR increased CFM by up to 12% over stock! The overall shape and design of the filter looks similar to the factory unit, due to its location, but internally features several enhancements to provide increased airflow beyond changing filter media alone.

Next the turbocharger plenum was upgraded. The factory plenum is tiny and features a flow restricting split-body design. APR did away with this and made theirs a large and organically shaped single-body design to promote airflow. Carbon fiber was used not only because it looks great, but it allows for thin walls and complex geometry to maximize cross sectional area. This aids in airflow and reduces pressure drop. The plenum is dramatically larger than the factory unit in various areas and is a single-piece design that extends past the integrated PCV and EVAP bungs, and runs all the way down to new billet aluminum high flow turbocharger inlets.

The billet aluminum turbocharger inlets feature bell mouth profile to promote airflow. If upgrading to larger turbochargers, the inlets can be modified or replaced to match the compressor cover on the new turbochargers. Furthermore, this system integrates PCV and EVAP bungs for a smooth install. New EVAP jet pumps were created and supplied for proper emission controls.

All of these improvements result in an upgrade that’s worthy to grace the 4.0T’s engine bay. The intake system lets the engine breathe more freely to maximize performance and gives a subtle but enhanced engine note that’s sure to delight the decerning ear! Go APR!
