For the customer who demands quality and performance, IE's new Audi B9 S4/S5 Intake System delivers on power, sound, and quality wrapped up into a product that reflects the Audi S trim as a true performance machine. IE's engineers took a "no expense spared" approach to design the ultimate intake system solution that delivers on looks, fit, and most importantly -power!

PERFORMANCE

Back to back dyno testing shows consistent power gains across the entire RPM band with +16HP and +16TQ over the stock intake without any additional hardware upgrades.

CARBON FIBER

Carbon fiber construction was used to create complex shapes and angles that can not be achieved with sheet metal bends. This design style utilizes every millimeter available in the oddly shaped modern engine bay for a very large air supply and smooth delivery.

VELOCITY STACK

The bell mouth shape channels airflow from the large internal airbox into the turbocharger as quickly as possible. This velocity stack creates a very high inertia flow from the massive 5" filter with very low drag or power-robbing turbulence.

FLOW TESTING

Back to back flow bench results show constant and consistent CFM (cubic feet per minute) gains over stock at any test pressure (in/H20). This data means the engine is able to take advantage of larger airflow across the entire RPM band
