Charge Pipe & Boost Pipe for BMW 1 Series 3 Series (2012-2018) 4 Series (2013-2016) 2.0L Turbo

High-Flow Aluminum Charge Pipe & Boost Pipe for 2012-2018 BMW 1 Series, 3 Series, 4 Series (N20/N26)

Replaces the failure-prone factory plastic intake piping with mandrel-bent 6061 aluminum to ensure consistent boost pressure and eliminate intake tract ruptures.

The Stock N20/N26 Charge Pipe Weakness

The OEM intake charge pipe is constructed from thin-walled, heat-molded plastic that is susceptible to fatigue from constant thermal cycling and pressure fluctuations. Over time, the plastic becomes extremely brittle, specifically at the throttle body connection point and the MAP sensor flange. Under increased boost—whether from spirited driving or aftermarket ECU tuning—the factory pipe often cracks or completely shatters at the locking clip groove. This results in immediate boost leaks, limp mode, and the risk of plastic shards entering the intake manifold. Furthermore, the stock design features restrictive internal geometry that creates turbulent airflow, hindering the efficiency of the twin-scroll turbocharger.

The Engineering Solution

This upgrade kit utilizes aircraft-grade 6061-T6 aluminum tubing, providing a rigid, non-expanding structure that maintains internal volume under high-pressure conditions. The mandrel-bent piping ensures smooth transitions and a uniform diameter, significantly reducing air turbulence and turbo lag for sharper throttle response. A precision CNC-machined throttle body flange retains the factory O-ring seal and locking clip, providing a secure, leak-free connection that is vastly superior to aftermarket silicone-only solutions. The kit includes heavy-duty T-bolt clamps and reinforced silicone couplers to ensure that the intercooler connections remain intact even at elevated PSI levels. The MAP sensor flange is also CNC-machined to prevent vacuum or pressure leaks at the sensor mounting point.

The BMW Precision Standard

Engineered for perfect fitment and zero Check Engine Lights (CEL), this kit maintains all factory sensor locations and mounting points. The aluminum construction resists heat soak more effectively than plastic, ensuring that intake temperatures remain stable during high-load operation. This is a critical preventive maintenance upgrade for any N20 or N26 powered BMW.

Common Questions

Will this charge and boost pipe kit fit my 2015 BMW 328i or 428i?
Yes, this kit is built for rear-wheel-drive 2012-2016 BMW 125i (international F20/F21), 2012-2018 320i, 2012-2016 328i, and 2013-2016 420i (international) and 428i models equipped with the 2.0L N20 or N26 turbocharged engine.

Does this kit fit xDrive all-wheel-drive models?
This kit is designed specifically for rear-wheel-drive (RWD) N20 and N26 models.

What is included in the kit?
The kit includes mandrel-bent 6061-T6 aluminum charge and boost piping with precision CNC-machined throttle body and MAP sensor flanges, reinforced silicone couplers, and heavy-duty T-bolt clamps.

How does this connect to the factory throttle body?
The precision CNC-machined throttle body flange is built to reuse your factory O-ring seal and locking clip for a secure, leak-free connection under boost.

How does the MAP sensor mount to the new pipe?
The piping retains all factory sensor locations and mounting points, including a precision CNC-machined MAP sensor flange to prevent vacuum or pressure leaks at the mounting point.
