The ARM 4.0T Stage 2 Intake System allows your Audi 4.0T turbos to breathe better by removing the restriction of airflow to the turbochargers. The Audi 4.0T Stage 2 Intake System is comprised of two primary components, the first is the intake portion, the second is the turbo inlets. When you upgrade both of these components you will have replaced your entire induction system.
The inlet portion of the intake system is the most critical component of the induction system as it is the main bottle-neck in the OEM design. The intake portion of the induction system (the filters and intake runner tubes) must be paired with the inlets to meet the requirements of running Stage 2 and higher tunes. This is considered Stage 2 Intake upgrade (Intake + Inlets).
ARM Inlets - When you order the ARM Stage 2 Intake System you will be provided with the ARM full billet inlet kit with the appropriate couplers to connect your ARM Inlets with your ARM Intake. The ARM 4.0T Inlets measure an oversized 62mm in diameter, making them a perfect for OEM all the way up to +4mm upgraded turbos. Upgraded Inlets are required for most Stage 2 and higher tunes.
Heat Shield - To maximize the amount of cold air going going to your engine the ARM 4.0T Stage 2 Intake System includes the additional ARM Heat Shield which separates the cold air feeding the intake filters, from the hot air generated by the engine. This will result in cooler intake air temperatures. The ARM 4.0T Heat Shield makes a tight seal to the hood, maximizing the amount of cold air being ingested by the ARM 4.0T Intake system.
Whether you're looking to test the limits of your 4.0T, or simply seeking to help your turbos breathe better, the ARM 4.0T Stage 2 Intake System gets the job done. Combining improved airflow, better power, and enhanced turbo sounds, this intake system delivers for your Audi 4.0T.
Very happy how they look and sound great too.
