BMW F Series 2.0 B37 / B47 Performance Induction Kit / Cold Air Intake Kit

Darkside Developements Custom 80mm Performance Induction / Cold Air Intake Kit for F Series B37 / B47 1.5 & 2.0 Diesel Engines

The perfect performance upgrade to replace the standard restrictive airbox and filter found on the B37 / B47 1.5 & 2.0 Diesel Engines

Our custom made intake kit features a unique Darkside heatshield / airbox lid which mates up effortlessly with the lower airbox clips.

Paired with the PRORAM x Darkside Pleated Dryflow Filter, this kit will offer increased performance and airflow over the stock intake system.

An open air induction kit will give your car that ever needed increase in induction, while the laser cut heat shield will reduce heat soak coming from the engine. This in turn will give the vehicle an increase in BHP and more importantly torque.

• Increased performance and driveability
• Increased Airflow
• Designed to increase horsepower and throttle response
• Designed and Manufactured in the UK

Please note this kit uses a Rectangular MAF boss, some N47 engines have an Oval shape MAF Sensor which we have a kit listed below.

Please Note:

Some vehicles may encounter a light on the dash once this kit has been fitted, the MAF may need calibrating to account for the extra airflow. MAF scaling guide

1x Darkside Aluminum Heatshield
1x PRORAM Dryflow Air Filter
