Overview

The MAD BMW G Chassis B58 Inlet is a turbo inlet pipe designed to optimize airflow from the intake to the turbo. It eliminates restrictions and increases the inlet diameter for improved power and turbo efficiency. The aluminum construction replaces the stock plastic unit, which can be prone to cracks and features a flow-hindering resonator.

Show original supplier description

The MAD BMW G Chassis B58 Inlet (MAD-078) is engineered to optimize airflow to your G-chassis B58 engine by replacing the restrictive factory turbo inlet pipe and resonator. The factory turbo inlet is typically made of plastic and can be prone to cracks, in addition to featuring a performance-hindering "resonator." The MAD inlet pipe, constructed from durable aluminum with an anodized black finish, directly replaces this OEM component. It eliminates the restrictive resonator and offers a wider diameter, promoting smoother and more direct airflow to the turbocharger. This modification also contributes to an enhanced induction sound, providing a more engaging auditory experience. Key features and benefits include boosted turbo airflow, enhanced engine responsiveness, and a construction that surpasses the stock plastic inlet. The design maintains an understated OEM appearance while delivering performance gains. It is compatible with a wide range of BMW G-chassis models equipped with the B58 3.0L engine, including various 5 Series, 7 Series, 8 Series, X3, X4, X5, X6, and X7 variants.
