The ARM G20 B58 Intake isn't your standard B58 intake upgrade. The ARM G20 B58 Intake is designed with a full 4" diameter throughout, making it the largest B58 intake available for the G-series platform. The larger 4" bore and reduced restriction of the ARM G20 B58 Intake allows your turbo to spool faster, which translates directly into sharper throttle response and improved power delivery, especially on tuned B58's. Installing the ARM G20 B58 Intake will also transform the sound of your B58. You can expect to hear significantly increased turbo spool volume on acceleration and a very audible venting of charge air when lifting off the throttle, bringing out the character of the B58 that the factory airbox keeps completely hidden.
The ARM G20 B58 Intake utilizes an inverted filter design which gives it a massive 186 cubic inches of surface area. Paired with our multimedia filter material which allows for superb airflow while providing impressive filtration and you have a combination that can support your B58 build no matter how far you want to take it.
The filter in the ARM G20 B58 Intake is protected from excessive engine heat by the aluminum heat shield surrounding it. Included in the ARM G20 B58 Intake kit is an aluminum heat shield cover finished in matching wrinkle black. The T6061 aluminum MAF pipe is a full 4" throughout, providing maximum airflow to the B58's turbo inlet and ensuring your induction system is never a limiting factor regardless of power level. Engineered with a precision CNC machined MAF flange for a precise and tight fit for the MAF sensor, secured by the two included bolt.
The ARM G20 B58 MAF pipe is connected to the B58 inlet via the 4" 6-layer reinforced silicone coupler ensuring a tight and leak free seal to the B58 turbo inlet. The ARM G20 B58 Intake is designed to connect to the OEM turbo inlet.
The ARM G20 B58 Intake delivers with the larger 4" bore, opening up airflow the factory intake was holding back, unlocking additional power and giving your B58 the sharper throttle response and faster spool it's capable of. The sound transformation is immediate, significantly more turbo sound on acceleration and an aggressive blow-off on throttle lift that the OEM airbox completely suppresses. Built from T6061 aluminum and 6-layer reinforced silicone with a powder coated heat shield, every component is engineered to fit and finish at the same level as the rest of your G-series engine bay.
