Charge Pipe & Boost Pipe for BMW 1 Series 3 Series (2011-2015) 4 Series (2013-2016) 2.0L Turbo

High-Flow Charge Pipe & Boost Pipe for 2011-2016 BMW 2.0L Turbo (N20/N26)

What it Does: This performance induction kit replaces the restrictive and failure-prone plastic factory charge pipes with high-strength mandrel-bent aluminum to ensure reliable boost pressure and improved throttle response.

The Stock 1, 3, and 4 Series Weakness

The BMW N20 and N26 engines utilized in the F20, F21, F30, F31, and F32 chassis rely on OEM charge pipes constructed from thin-walled thermoplastic. Over time, constant heat cycling from the turbocharger and engine bay temperature fluctuations causes this plastic to become extremely brittle. Under increased boost loads—especially on tuned vehicles—the factory pipe often fractures at the throttle body flange or the intercooler connection. These structural failures result in immediate boost leaks, 'drivetrain malfunction' errors, and the risk of plastic shards entering the intake tract. Furthermore, the OEM piping features restrictive bellows and non-uniform diameters that create internal turbulence, increasing turbo lag and hindering airflow efficiency.

The Engineering Solution

This upgrade utilizes 3-inch high-grade 6061 mandrel-bent aluminum piping to maintain a consistent diameter and smooth internal surface area. By eliminating the factory's accordion-style flex sections, airflow dynamics are optimized, leading to a significant reduction in turbo lag and crisper throttle tip-in. Each pipe features a specialized wrinkle-black heat-insulation coating to resist heat soak and maintain cooler intake charge temperatures. For enthusiasts seeking higher performance ceilings, the kit includes integrated 1/8” NPT bungs, allowing for the seamless addition of water-methanol or nitrous injection. The precision-machined throttle body connection ensures a leak-free seal even under high-pressure conditions, providing the structural integrity required for both stock and high-boost applications.

Common Questions

Will this charge and boost pipe kit fit my BMW 328i or 428i with the 2.0L turbo engine?
Yes. This kit is built for 2011-2015 BMW 1 Series (international F20/F21 125i) and 3 Series (F30/F31 320i, 328i, including international 2011 models), plus 2013-2016 BMW 4 Series (F32 428i and international 420i) equipped with the N20 or N26 2.0L single-turbo engine.

Does this fit a US-spec BMW 128i with the 3.0L inline-6 engine?
This kit is engineered specifically for the N20 and N26 2.0L 4-cylinder single-turbo engines.

What is the piping made from and what size is it?
The pipes are constructed from 3-inch high-grade 6061 mandrel-bent aluminum with a wrinkle-black heat-insulation coating and a precision-machined throttle body flange.

Does the pipe include ports for water-methanol injection?
Yes. The piping features integrated 1/8-inch NPT bungs to support water-methanol or nitrous injection setups.

Are permanent modifications required for installation?
It installs as a direct replacement for the factory plastic charge and boost pipes, maintaining factory-like fitment with no permanent modifications required.
