For this application we have opted for a smooth one-piece expanding inlet tube with integrated MAF attaching directly to the inlet tubes with silicone couplers.  The expanding large volume inlet tube acts like a large velocity stack which accelerates the airflow and is much larger than the small and short velocity stack fitted to the internals of the OEM intake.

The result of the smoother airflow from our inlet tube is a far smoother lower rpm torque availability from the engine vastly improving drivability.  Throttle response is immediately felt to be smoother and more eager. The inlet tube is attached via a stainless steel v band clamp to the air filter housing which attaches directly to the oem front air feed and has a 100mm opening facing towards the front corners of the engine bay rather than facing downwards towards the wheel arch liner away from engine heat.

15-25hp is gained through the rpm range with excellent gains below 3000rpm which can be attributed to the smooth elongated design of the intake tube which accelerates and smooths out the airflow.  This gain is very much apparent under real world driving conditions under both partial and full load with a much smoother power delivery.The next area where the expected majority of the improvements are seen are from 4750rpm to 7200rpm.
