SLE Intake System – BMW 340i / 440i F30 / F32 / F36 (B58 Gen 1) 2016–2019

Description:
The SLE Intake System is designed to bring performance, sound, and style to your B58-powered BMW 340i or 440i. This system replaces the restrictive factory airbox with a high-flow, mandrel-bent aluminum intake pipe and a large inverted cone air filter, delivering improved throttle response and enhanced turbo spool.

A precision-fit heatshield separates the intake from engine bay heat, keeping IATs low for consistent performance. The result? Sharper response, louder turbo and bypass valve sounds, and real gains you can feel — especially when paired with a tune.

Finished in a wrinkle black powder coat for an OEM+ look, this is one of the best bang-for-buck mods for Gen 1 B58 cars.

Features:

• Mandrel-bent aluminum intake pipe (wrinkle black finish)

• Large inverted cone filter for maximum airflow

• Laser-cut aluminum heatshield with rubber trim

• Improved throttle response and turbo spool

• Aggressive turbo and BOV sound

• Bolt-on installation — no tuning required

• Compatible with stock or tuned vehicles

Fitment – B58 Gen 1 (2016–2019):

• BMW 340i / 340i xDrive – F30 Sedan

• BMW 440i / 440i xDrive – F32 Coupe / F36 Gran Coupe

Note: Fits Gen 1 B58 models only. Not compatible with 2020+ Gen 2 B58 engines.
