Performance Cold Air Intake System for BMW N20 / N26 2.0L Turbo

Unleash the Hidden Performance in Your BMW's Turbocharged Four-Cylinder

When BMW introduced the N20 engine in 2011, it earned a spot on Ward's Top 10 Engines list —a testament to its advanced engineering. This 2.0L turbocharged four-cylinder was designed to replace the naturally aspirated six-cylinder N52/N53, producing similar horsepower with greater low-rpm torque and better efficiency . But there's untapped potential waiting to be freed.

Our sealed cold air intake system is engineered specifically to maximize the N20/N26's capabilities by addressing one critical limitation: airflow restriction. Factory dyno testing reveals the N20 is actually underrated, producing around 275hp and 290 lb-ft at the crank in 28i variants —more than the advertised 241hp. With improved airflow feeding your twin-scroll turbocharger, this intake unlocks measurable gains in horsepower, torque, and throttle response across the entire RPM range.

Why Your BMW Needs This Upgrade

The BMW N20 is extremely receptive to modifications, making it relatively easy to achieve 350+ wheel horsepower with the right combination of parts. This cold air intake is the foundational upgrade that improves breathing efficiency without requiring immediate ECU tuning—though pairing it with a tune will maximize your gains.

The system replaces your restrictive factory intake with a 3.5" high-flow aluminum path that delivers cooler, denser air directly to the turbocharger. The sealed, insulated air box integrates with the factory air scoop to force cold air into the intake while minimizing heat soak from the engine bay—critical for maintaining consistent performance during spirited driving or track sessions.

Key Features

• High-Flow Induction: 3.5" mandrel-bent aluminum intake tube with black powder-coated finish reduces airflow restriction significantly over the factory plastic system.
• Sealed Air Box Design: Insulated construction prevents radiant engine heat from warming the intake charge; integrates seamlessly with the OEM air scoop for maximum cold air delivery.
• Advanced Filtration: Inverted cone air filter design provides larger surface area for improved breathing while maintaining excellent filtration—washable and reusable for life.
• Precision Hardware: Includes billet SAI (Secondary Air Injection) breather adapter and filter, plus a reinforced billet mounting bracket to eliminate rattling during high torque loads.
• Race-Inspired Sound: Delivers an aggressive, turbocharged induction note under boost that transforms the driving experience.
• No Tune Required: Engineered to work with factory ECU parameters, though a tune will unlock additional performance gains.

Performance Benefits You'll Feel

• Improved Turbo Response: Reduced intake restriction means your turbocharger spools faster with less lag.
• More Power Throughout the RPM Range: Cooler, denser air optimizes combustion efficiency for measurable horsepower and torque gains.
• Enhanced Throttle Sensitivity: Sharper acceleration response from the pedal, especially noticeable during highway merges and passing maneuvers.
• Better Heat Management: The sealed air box keeps intake temperatures lower, maintaining consistent performance even during extended high-load driving.
• Foundation for Future Upgrades: Pairs perfectly with an upgraded downpipe and tune to build toward that 350+ wheel horsepower target.

Installation

Designed for straightforward installation by enthusiasts with basic mechanical skills. Most installations are completed in 1-2 hours using common hand tools.

Installation Tip: See Guide - Disconnect your battery's NEGATIVE terminal before beginning installation. After completing the install, leave the battery disconnected for at least 60 seconds to allow the ECU to reset and adapt to the increased airflow. This optimization helps prevent check engine light errors and ensures maximum performance gains. Always perform installation on a completely cool engine.

Perfect For:

• Daily drivers seeking improved throttle response and efficiency
• Enthusiasts building toward a comprehensive bolt-on package
• Track day warriors who need consistent performance under load
• BMW owners planning future upgrades (downpipe, tune, turbo upgrade)

Build Your Performance Package: This intake pairs perfectly with an upgraded downpipe and ECU tune to unlock the N20/N26's true potential. With proper supporting modifications and conservative tuning, the N20 can deliver 300+ horsepower and torque —transforming your BMW into a powerful, responsive, and fuel-efficient driving machine.
